Just drive the thing and keep oil in it! After I work all the bugs out I might cherry the body out a bit and paint it. But for right now I love it! There is nothing like driving it to Starbucks and having a WWII vet coming up to you and telling you war stories about rolling over two flat fenders during the battle of the bulge!!! I have had my fair share of jeeps over the years. As far as rigs go that don't really get wheeled, this thing is the most FUN!!!!!!!
Ok, Ok, I know everything... The Kiaser engine is the same as the willys L-head. It was produced by Contenental and was origanlaly an impliment engine designed for stationary work in water pumps and such. It was even used in fork lifts. From 1951 to 1953 they were put in the Kaiser Henery J and version sold by Sears via catalog called the Allstate. The differance is the lettering on the head. And yes it is possible to interchancge the heads, you may still have a willys engine with a kaiser head as they were infomous for warping and cracking. Do a search for the Kaiser Owners Assoc. for info.
