I recieved my uppers and they didnt give me the bolts to go through the bracket/cross shaft. They did provide the nuts. Can you guys tell me what size hardware these are specifically the length since theres probably some shimming involved. Any assembly tips?

The coils for the coil over conversion, what is the best way to install these small diameter coils. I dont think my coil compressor will work with these. What tool do I need?

Any assembly suggestions are appreciated, Thanks

Rich

if you are talking about the studs that hold the upper arm to the subframe, then you can get them from GM- you just need to get one of the "senior" parts guys to find the stuff for ya. each stud will run a couple bucks- figure $10 for all 2 of them.
or, if your existing studs are good, why not use them?

4-bolts, they go through the cross shaft and through the frame bracket, holds the whole upper A-arm assy to the frame.

yep those are the ones that novederrik is talking about. I also agree with what he stated.

Rich,

The stock bolts work fine. If yours are missing/damaged you can order them from any of the restoration guys.

The springs on the coil overs usually can be installed by hand. There is a spanner wrench I'd recommend for adjusting the spring/car height which is available from Summit and most chassis shops or vendors. But all the coilovers I've had have not required any compressors to get the springs on.

Thanks nova/brian/jodi,

You guys through me off calling the hardware studs. when I disassembled the uppers on my sub, they were held on with bolts. So the hardware is threaded on both sides of the crossshaft and bracket. The interesting thing is when I look at the completed projects at the dse website it looks like they use a machine bolt and nut the cross shaft side.

I will order the spanner from summit.

Thanks again guys

GM actually used studs to hold the cross shaft to the frame- they look like a long coarse thread 7/16" wheel stud, except for the 11/16" hex head on the back side in case the knurls don't hold and the stud starts to spin when loosening crimp locking nuts during an alignment.
i'd get them from GM- the resto houses sell the same part, but charge you extra for the priviledge of ordering from them and waiting a week to get them. most GM dealers can get them the next day- or might even stock them. i've got the part number somewhere around here- here it is- part number 381909 which lists at $4 a piece, but i got them for $2.54 each.
