I've put a whopping 7 miles on it without a single miss, hiccup, or
stalling ... but I ain't holding my breath.

I hated doing the front bushings myself and I'm glad I don't have the
rear 4 link suspension for that reason.

While I had it down for the other stuff I converted to an open cooling
system instead of the closed system that sent 20% or more of the hot
engine coolant thru the pressure bottle (now my overflow tank) and
bypassed the radiator and heater cores ... no wonder Renix engines run
HOT!!!!

We're looking at a '92 parts XJ (no title) for patch panels but if it is
in good enough shape, we may try to get a replacement title and drive it.
