Thanks for the contact Tony, let us know how the install/test run goes!
My 29 year old Cobra is still running & shifting great, but I like to keep options open. When the time comes, I can do one of several things:
get rebuilt Cobra (my local guy in Northport still does them), they are also available from several on line sources.
convert to a Volvo SX (more money but smoother shifting cone clutch, and better re-sale down the road)
convert to SEI, or use their kit to convert to a rebuilt Alpha.
I like the Cobra because I can do all the maintenance on it and they really do last a LONG time when set up properly. Prob go with option 1.
