Suregrip issues?

FYI you can rebuild the clutch unit.
Depending on the type, the Dana sure grip that has the V-ramp to lock the clutches can take allot of abuse.
Chrysler used them up to 1968.
The aftermarket spring type is not the best but better than cone.
Spools aren't the best if you do allot of street driving.Occasional street use is your discretion.
Your car is really light.
