so me and my brother were talking and i was telling him i was going to put in a moser or dana rear end but then i got to thinking... would corvette rear ends bolt up to third gens? has any one tried it at all?

Bolt up? How? There's a thread going right now in fabrication about a C4 Dana44HD install

The only rear-end that will bolt up is one that's specifically for a third- or fourth-gen F body. Anything else requires fabrication or suspension modification.

I'll be posting updated pics Monday night. It's a direct bolt in...

it is, after you do a ton of fab work, then it bolts right in!

ain't that the truth

No seriously, bolts right in with minor trimming required....

BUMP........... I HAVE A TON OF PIC"S of a Fellow 3rdGens car. I will be uploading later for everyone to see so it is documented with good pic's for future people searching TGO for it.

A search for IRS , Independent rear end , corvette rear end , should all show up in a search and find this post for people now.

I have a TON of other 3rdGen pic's on my site also so will mirror the pic's there also.

I'd love to see them....

I thought you were going to actually show someone else's car....

You're missing a few pics by the way...

lol i never said whos car. lol.... I'll dig out the other ones some day. They are of a yellow 3rd gen with a irs also. it was posted here years ago.

They yellow one is the one I remember seeing years ago as well. I've desperately tried to find them online again and can't find them anywhere. I know they used to be on this site, but I think the links are dead now. he is the only other guy I've seen besides myself that re-used the corvette trailing arms. If I recall the yellow car is a convertible with no roll bar, so I'd like to see how he reinforced the trailing arm boxes.

There are pics of another thridgen running around on here but they are all undercarriage shots with the car on the ground and you can't really see how anything was done.

ya, I had the pic'sof the yellow vert linked and then cleaned house on my server. I have a extra terabyte hd around here I'll have to dig out with them on it still.

I have the green GTA with it done also. Just a matter of me diggin out the HD and searching thru all the pic's/folders to find em.

Wow, i never knew there was a GTA with it done. That must be this one?

Huh... Ok, what the heck was all the noise in that other thread about?

I like how your main hoop fits... is that custom bent or is that from a kit?

what are you referring to? The pix above are not of my car. Are you talking about my main hoop? Where did you see it?

OH duh, you're talking about the pictures TPI 383 posted. He saved those while my other thread was still up. I can't control what he posts, he saved them on his own. All I can say is that the project is quite a bit farther along now than the pix show.

I'm on probation and can't edit my posts. I don't know what that proves but whatever

The main hoop is custom, as is the rest of the roll bar. Nothing was "store bought"

Now you are ready for the ultimate 5-link coilover setup.

Dean is that setup for a C4? I don't recognize those knuckles at all...

No, its for my C3. I sent you a reply on PM.
I just posted that as an example of what a great aftermerket Vettes have. The C4 setup from the factory are very nice. The only real weakness is the rear tierods flexing. Just replace them with solid hiem links. I read your post and you are alot better off using the coilovers than the upsidedown leaf. The leafs "unload' the rearend faster on heavy braking and corner set. They are heavy duty though for massive HP which I run. I have always driven my Vette with lots of throttle induced rotation. Years ago I developed a clamp setup for my leaf springs. Guldtrand copied my design and sells them (I used to reace for DickGulstrand, I have known him since I was a young kid, I grew up on THunder Alley in Culver City many a days running through his shop. I raced on his Solo team back in 87-93 and basically had no competition so I never further developed my rear suspension past the multiple sets of rear leafs we combined to get the feel on the rear I needed for stabilty- I ended up clamping them and fond they helped not unloading in lateral set- god help me once I had a clamp break and I spun at about 95mph in a high speed left hand sweeper. I went around twice- what a ride, I will never forget that, I was about 24 at the time. Luckily I didn't hit anything and stayed fairly centered on the track as it spun. I was amazed how I could control the car's position even though I could not stop the spin- but I never whant to try that purposely.

ps- Diick still has a picture of my Vette in his gallery webpage;

In the second pic you can see my leaf spring clamps. I can adjust spring rate slightly by repositioning them laterally

Mind sharing?

As nice as the guldstrand setup is (I have one new in the box lying here) the greenwood setup was just a tad nicer IMO. The guldstrand piece uses 2 widely spaced lower camber rods where the toe is set and controlled by the front rod setting in respect to the rear. The greenwood setup was more like the C4 setup but it used properly located and sized toe control rods, not a center hung/mount setup with long toe rods like the C4 has (which is only accurate around static ride height with the rods around horizontal for reduced angular effect on effective horizontal component, much like the issue with the panhard bar in lowered cars) The guldstrand setup does have this beautiful siomplicity. Getting the 2 camber rods right is a no brainer and having them control the toe is down right genius. The greenwood setup was a lot more difficult to design as the toe control rod had to be in the same plane as the halfshaft and have length and pivot locations that geometrically work with the halfshafts to properly and accurately control toe throughout susp. travel. The greenwood stuff is all fabbed from stock and sheet metal. The Riley/Scott Protofab unit was like that too. The GS one has nice cast hubs as you know, excellent quality Only downside IMO is that GS doesn't recommend running coil overs on it. With a support bracket it might be doable.



Even nicer is the Greenwood adjustable double a arm suspension with coil overs. IMO that is the pinnacle of aftermarket C3 suspensions. Too bad it's not available and pretty rare. There's a somewhat molested C3 w/ greenwood GT body on ebay every now & then. I think it's the real deal as it still has some of the greenwood specific items like a boost gauge (now has a big block), the badges wheels, body panels and most interesting this very same sheet metal fabbed a arm susp



Nice vette you have there explains the name vetruck
