Well, my parts arrived, and the GM "anchor plate" is in fact the same as the Guldstrand bracket. It is part number 18016034 and costs $55.54 from GMPartsDirect.com. Here are some pics of the parts.



Oooh, aluminum driveshaft too! Dont forget to buy the bolts and washers when you place your order. PN's 10268875, 11508133, and 14084051. 4 of each required.

Thats great news... thanks for the part numbers on the bolts and washers. I could kick myself for throwing away the spindles from my 91. I could have set it up and just bolted them on.

Great Stuff.

Now, bolt it on, and THROW OUT THE ANCHOR!
What kind of brake pads are you going to use? Performance Friction has the Z-rated pad, great for serious street duty, and Hawk has the HP-Plus. Either of these will be a great pad.
Keep us posted on your progress.

Oh and please excuse me for this but I have to add an "I told ya so" cause I was right about the brackets and spindles and stuff, so I TOLD YA SO! sorry.

Yeah Karl you were definetly right! From what I see, I have to drill and tap two holes on the spindles to 1/2"-16? Other than that and cutting the caliper ears off, no other modifications to the spindle are necessary right?

I'm using Autospecialty Metal-Lux pads. They're supposedly low dust and squeal. I'm using Autospecialty rotors too so we'll see how they work out. If I'm not satisfied with them I'll probably just go for Pagid or PFC. Most of my driving is spirited street, so I don't want to sacrifice cold performance for a pad that bites like Mike Tyson when they're hot. Every once in a while I'll have to bring the car down from 100 into a quick off ramp, but other than that it doesn't get beat too hard. Thanks for the help and advice!

I would double check the bolts you have because most of the bolts on our cars is metric. I order the same parts as you did and i believethe two center bolts are 14mm-1.75 pitch and the two outer blots are 12mm-1.75 pitch. I do have a ? for you how does the cradle mount to the anchor? does the anchor go to the inside or outside of the cradle?

 

Tad,

You're right, they are metric bolts. I had to think twice myself.

The anchor plate bolts to the spindle and when you put the rotor on, it actually goes over the anchor plate a bit. On the backside of the rotor, there is a void between the hub and the friction surface, and the anchor plate sits about 1/4" into the void. Once the rotor is installed and bearings adjusted, the cradle installs over the rotor and attatches to the back side of the anchor plate (towards the engine bay). The center two holes on the anchor plate are threaded and the bolts go through the cradle and into the anchor plate.

When you get the parts and mock everything up, you'll see that the cradle can only go on one way. Basically the only thing that can possibly be screwed up is that the anchor plate could be installed backwards. But when you see it you'll note the little protrusions on the backside that contact the spindle and cradle. When installed, the anchor plate will have the part numbers facing outwards. HTH.

Thanks Jasons it was a little hard to image because I don't have my rotors yet. Just one more ? does the dimbles face the spindle or the rotor? Thanks again.

 

Never mind the ? I figure it out after I read your respone agian.

 

thats good news and a good time to update Pauls Tech article to include this info
The article is pretty good I followed it and found two problems: the source for brackets and the Brake hose bolt PN is 10286122- its called a fitting (its just a banjo bolt), cost $2.45
heres the article- http://www.isthq.com/~dan/1LEbrake.html

 

CAn you list the parts and the prices so I can get a idea of what it is going to cost, thanks alot joe

Well guys, I probably won't get around to the retrofit for at least a month, but I'm willing to document my work and take pictures to make an article with. Hopefully I can submit it to Dirk and we can get it on the site sometime. Thanks for all the help everyone.

I have attemted to install the GM bracket on my stock (non 1LE) spindles. And it would not bolt up. without some drilling and taaping,as you have mentioned.But! I believe the "GULDSTRAND" brackets do not require any drilling or tapping of the spindles. I believe that for the money and to save all the extra hassle. The guldstrand brackets are a better deal.

You HAVE TO drill and tap.

Those dinky little bolts that normally hold the dust shield/backing plate to the spindle are not nearly strong enough to handle the forces of braking. If the gulstrand brackets do indeed use the small bolts then I would never put them on anyway for fear of death.

Buy a drill bit and a tap of the correct size and do it right. It will take less than 10 minutes to do both spindles and you will have the peace of mind knowing that it will not fall apart the first time you jump on the brakes.

I agree..the Guldstrand brackets would have to be drilled and tapped as well.

I had heard the Guildstrand brackets were no longer available. How were you going to get them????

It may be slightly off the topic, but does converting to 1-LE front brakes this way still move the tires out? I would like to convert mine, but my wheel and tire combo slightly scrapes the outside of the wheel-wells now! Don't want to change rims and tires.

 

I believe that somebody else has addressed this question and they decided that it did not relocate the wheel appreciably....
