Aluminum Cross Member Mounts/Problem and has anyone tried these

[AmadeusCharger500]

I ordered new bushings from Firm Feel. It seems they were out of the Rubber and sold me a discount set of the newly designed Aluminum/Steel Bushing. All is cool except for the fact the mounting bolts are 1/2 inch compared to the original 7/16. So do I go ahead and tap out new Threads and is it worth the upgrade(??) to aluminum?

Are you talking about the torsion bar cross-member mounts. If so I had the same problem. What I did was reuse the 7/16" bolts and hammered in a sleeve for the 7/16" bolt to go through to take up the space, its been fine so far.

Yeah these.

So what type of sleeve? Rubber or Metal and howd you fit it?

[bordin34]

Metal, I had it laying around from when I bought a sway bar. I cut it to length of the entire bushing and hammered it in.

Give em a call and see if theres a reason for he larger bots.

Called them. They were surprised and promised to make me a new set. Brought up the question, is the 3/8 bolt size sufficient to hold that crossmember to the frame. Well I guess it held for the life of the car so far!

I surprised nobody called them before. When I got mine I assumed that 75+ b-bodies used a bigger bolt and thats what they were made for so I just modified mine. Also the bolts are plenty strong, its what they screw into that flexes.
