A-8133, radiator support rods, two needed.

FWIW, The original rods used tight tolerance threads and tight tolerance threading on the nuts.

If you use a regular tap and die you make them loose.

I believe the lack of movement on the nuts ensured they stayed parallel and were less likely to get loose.

I have cracks in the fire wall on both rods so i needed to get them off to repair the firewall. I put a pair of wrenches on one and it snapped with next to no torque. I ordered a set of stainless ones.
