Sway Bar Bushings - '96 Grand Prix

[quakerj]

Need to replace the sway bar bushings on my '96 Grand Prix, but Rockauto shows a bunch of different sizes.  No earthly idea why GM would make all those sizes but I digress.

I took a digital caliper out and measured the bar on a straight portion between the subframe mount and the mount at the control arm.  It measures exactly 35mm.

The problem is that I can't find a bushing for a 35mm bar.  This is a '96 Grand Prix SE with the FE3 suspension, does anyone know what size bar it should have?

Rockauto lists 24mm to 36mm with seemingly endless sizes in between, EXCEPT a 35mm.  Is 36mm the one I should be after?  Any help would be greatly appreciated!

Also, does anyone know how these are removed, the ones at the subframe?  It looks like there's a through bolt coming from underneath the subframe that has a T50 torx head, then two nuts holding each cap at the top.  Problem is there's zero room to get a wrench in on the nuts-- I tried every tool I had, there's just no place to maneuver a tool in there..  I tried an impact on the bolt head with a T50 bit and it's just laughing at me.

If it IS a through bolt like I suspect, I guess if all else fails I could cut the bolt heads off which should free them, and then replace with another bolt?  Would love to hear how others have done this.

Quakerj maybe it would help if yo posted a picture of those fasteners.

My 96 Regal has a smaller 30 mm bar and just a regular hex head bolt and nut set up.

1996 GP w/ FE3 suspension shows part number 10284183 for the inner bushings and 10152155 for the outer bushings. Should be about $30 for all four bushings from your local dealer.
