I have one in my '70 Challenger. Initial installation was a nightmare. It took several years to get it fully dialed in dialed in.
The third crossmember finally was close. I had to pay shipping to send it back for case mods so it would almost fit the car.
I had to jury rig one of the covers to get it to stop leaking. The pilot bearing kept falling out.

What are your issues?
