Willys CJ-3A DIY Bow Bar Kit:
I decided that I wanted to run a Best Top bikini top, Part# 52507-01 for ’76-’83 CJ-5, on my 1950 CJ-3A. I picked this bikini top because I found that it was 3″ narrower and fit the CJ-3A windshield perfectly. Reading the current Q&A on Kaiser Willys, there wasn’t a good way to run a bikini top without a roll bar. I engineered a simple DIY kit that consists of 1.00″ O.D. round tubing, black rubber crutch tips, and brass flag grommets. The attached .pdf engineering drawing shows the profile of the bent tubing, and the .250″ pins that locate through the brass grommets. The outcome looks great and works perfect. The tube assembly can be erected in minutes and stows nicely in the tailgate area of your Willys.
