Ok, I am sick and tired of driving around town looking for these damn bolts. I bought 4 from the Home Depot here only to find out the bolts in the packages are not 1.25 thread. I now have 4 40mm 8 . 8 grade that I got from ACE Hardware and 4 45mm
10 . 9 grade automotive bolts that I got from Pep Boys. The only bad thing about the Pep Boys bolts are the threads only are about halfway up the bolt as you can see in the pics.... I am most likely going to just use the Pep Boys bolts since they are the strongest material. I am measuring the bolt and just under 1" has threads and another 1" without threads. This does NOT include the hex head. Just the shaft of the bolt. Since my camber is off 3 degrees in the rear I am most likely going to need 4-5 washers anyhow.

You'll have to use your imagination since I do not know how to copy pictures. At the time when I took the OEM bolt out I had the Home Depot 40mm lenght (wrong thread pitch) bolts. Those are the 2 bolts in the pic below:



Now here is another 40mm lenght bolt (right thread pitch) lined up against the Pep Boys bolt that is only threaded half way:



Here is another pic of the same 2 bolts showing the size of them. I covered the flash since it was causing a glare on the tape measure:



You can just imagine how much longer the 45mm is to the OEM bolt when looking at the pics. My main concern are the 1" of threads on the Pep Boys bolt. I don't think it will be a problem though since those bolts are really strong.

Here is a site that tells you about the grade / strength of bolts:

What do you think? Pep Boys bolts should be fine?

[i]Previewing Post: Actually, as I am previewing the pics it looks as if the OEM may only be threaded an inch or so. So, I think the Pep Boys bolts should work fine.... Anyone else see this? I am going to be doing this Monday, so hopefully I am seeing all this right...

 

here is the easy answer, stop beating yourself up.

Keep the arm in factory position and both bolts tightened snug. Then remove one bolt and then screw it back in by hand counting the number of times it turns a full revolution.

Then put how ever many washers you think you need. Then screw the bolts(which ever you think you need) back in counting the number of revolutions. If it is the same or more you are fine. If it is a few turns less then OEM you are fine.

I put one washer using my stock bolts. Its fine.

 

I just added 6 per bolt (Pep Boys bolts) and it straightened the $hit out of my rear wheels. Actually, too much! I bet it's about at 0 degrees and now my rear is rubbing on EVERY little bump. This is after I raised it up maybe a 1/4" of an inch because the rear had been sitting a little lower than the front. So, I am going to miss work today (I'm going to play dumb and act like I had the day off ) and have to go back out and remove 2 washers from each bolt

Pics will be up later
