I put the Casper oil filter adaptor on my Colt, very nice kit and the owner in Florida is very helpful. Be sure and also install the restrictor plate which is required for the 0-235, Casper also has these for sale. I also have the second, right fuel tank for 6+ hours range, dual landing lights, 60 amp alternator, autogas STC, droop tips (no longer available), Wag Aero shoulder harnesses (get the complete kit with STC) - these turned out nice and work well, wheel bearing caps to keep dirt out, new glareshield from this website. My wishlist includes Steve's STC gascolator, Dakota Cub fuel selector, Bogart battery box mod and cables, Rosen sunvisor kit, and sheepskin seat covers. Remember - all it takes is more money!
