Henry, As you may recall, I used to offer tar top battery reproductions, but they were all gone as of 1999. I have a couple of dead tar tops that I've been thinking about gutting and trying to covert as you describe by putting in an Optima battery. I have no idea if it would work. The next time I am in a parts store that sells Optima batteries, I'm going to take some measurements to see if it is doable. I still have quite a few reproduction battery labels, both early ('56-'58) and later ('59-'64). When I replaced the battery in my G two years ago, I bought a generic group 27 black poly case, solid top, from American Battery in Hayward, and removed all the labels and put a MoPar repro label on it. Looks pretty good, cost about $60, and has held up well with low maintenance. Bob J ------------------------ Yahoo! Groups Sponsor --------------------~--> Yahoo! Autos.
