2055 install on '83 LG4- spacers needed?

OK, so I think I can deal with the bolt I screwed up, and I realized I need 2 studs where the A/C and PS brackets go...
Can anyone tell me what size spacers I need for these 2 front driver's side bolts, or anyone have pics of 2055's on an LG4 or similar setup?

I didn't realize I'd have to deal with spacers, etc. Anyway, Thanks for any advice,
bubba

...before I f--ked up

Now what?

Re: Great- broke exhaust manifold bolt

Now the fun begins.

Seriously, continue taking the exhaust manifold off. There is still about 1-1/2 inches of stud left to grab onto. You only broke the head off.
Hopefully more don't break.

Re: Great- broke exhaust manifold bolt

Well, I got the bracket off. Now it looks like I have to take off the power steering pump bracket to get the front most stud out.
Then maybe I will use a "bolt out" to remove the stud on the right, unless the whole stud unscrews when I try to remove the 9/16 nut from it.

What really confuses me- I have no clue... what the hell kind of header bolts do I use to reconnect these brackets the way they were originally?! I bought a nice set of new 3/8" head, 1" depth header bolts from Summit, but for these 2 I need a different stud/ bolt to mount the bracket on?

I haven't seen this issue mentioned in any header install threads. I have looked for pictures of SBC's with 2055's installed, to see how others deal with this, but I haven't found any helpful photos....
Thanks very much for any advice!

EDIT: So these studs look like they would work, but I would need some kind of spacer also?

Search for some pics of SLP headers. They have the spacers already tack welded on.

Thanks for the advice... I have looked around, but am unable to find pics of installed SLP's, where you can see the spacers. They would be different from the Hooker 2055's anyway, no?

Re: 2055 install on '83 LG4- spacers needed?

measure the width of the manifold and compare to the header flange. you may have to cut a spacer to fit. for the forward bolt

you'll likely find that the bracket has to be cut as it won't fit around the header pipe for the second bolt.
