My brother went through 3 or 4 of the repops for his 70 Challenger and couldn't get any of them to stop leaking. So we found and paid up for an original set and he rebuilt them himself with the kits available from Musclecar Research.

If you're determined to replace your originals don't toss them out, they're worth $200-$300 these days as cores.

For 1973 the e-body proportioning valve changed to a different design.
