Scott,
I too run ProShocks on my E/M and I've run Pro's, Afco's, and now Penskes on my Late Model. On the dirt Late Model the left rear shock is used as a travel limiter - no cable. The left side of the car is topped out everywhere on the track except on except entry and none have leaked yet.

If your springs are loose at full sag (as mine are) you can use a
flat wire, "take-up spring", that Afco sells for that situation.
