I would buy these again if a shim pack was given w/ the kit.

I purchased Speedways forged front drilled 4" drop axle and these radius rods with holes as a kit. The issue I see is the inside measurement of the radius rods are 1-5/16" and the radius rod/perch mount boss on the axle measures 1-1/4". There is no spacer/shim pack with the kit. I don't want to tighten the spring perch bolts down to squeeze 1/16 of play on the radius arms. I called and they are looking into it. I hope Speedway sends me a shim pack to fix this issue.

Odd bung size

I bought these for my 1938 Ford project. They went on real nice and look good. My complaint is the rear mount heim thread size. It's 11/16-18. Try and find a quality heim in that size and find out how limited you are. They should have been a 3/4 thread. Other than that issue, I think they will be fine.
