[QUOTE=PSU 98] Well my first attempt didn't go so well Maybe someone can tell me the secret to getting the rear U-joint loose? 7mm is too big but 6mm is too small? 9/32 is too big but 1/4 is too small?? I was actually (somehow) able to remove the bolt and all the hardware with the driveshaft in place but it's just too difficult to work the mounts loose without getting the extra room in there. If anyone has been able to accomplish this on an '82 without removing the driveshaft, I'l buy you a drink [/QUOTE]

Are your bolts 12 points, or 6? I believe the 12 pointers are 1/4"...


[QUOTE=ossw1] Hey Apple as I was driving to work this morning I remember that I have a 81 assembly manual. [/QUOTE]


Don't cha jest HATE it when that happens? Adams' Apple2007-01-02 18:45:30

I believe they're twelve-point.  They seem to have a weird shape to them though, like a Torx bolt turned inside out   

That's IT!! They ARE inverted torx, 10mm, I think, maybe 8mm. I have the wrench for them, but it is in the storage building, in my tool box. I'll stop by in da morning and find out fer sure what size it is.
It sux losing yer memory...

I would really appreciate that Joel.  I know I don't have the correct sockets... I'm betting one of my friends does though  

Sounds like it may be a T45 Torx.  Mike

edit: I think the T45 uses an E14 socket.

  My 80' dosn't have the Inverted Torx I have never herd of such a Thing but thats when GM was trying a bunch of new fasteners. Dose Your 82' have Aluminum Camber Rods ?  Dose anybody have an 82 With Aluminum Camber Rods I saw one at a NCRS show in Arizona. Richard...

E-10 Torx fits my halfshaft joints. I think my driveshaft joiints were 1/4 inch 12 point. Why they are different, I don't know. U joints are the same. Changed the mount bushing last summer on my 82, and I had to take the driveshaft off the diff to get the bolt out. It gets easier the more you do it

I'm going to try again tomorrow with a fresh back and arms.  Maybe I can even get a pic of what I'm seeing.  I'm pretty sure that they are some sort of special bolt head.  They do not appear to be regular Torx screws.

They are either E8 or E10. That's the size of the wrenches I have.

That sure looks like it.  I don't think I could get a box end wrench in there though, there wasn't enough room to make a "sweep" so it'd probably have to be a socket.  I'll post up when I get this figured out, I'm also having problems with my DD at the moment so this could get put on hold for the time being    Thanks for all the help!
