I have read the CRG page on the batteries and I am wanting to make 100% certain that in 68 say a L30 4 speed car (or any other engine option aside from the 302 & 6cyl) could not have gotten the Y55 battery..
Not sure if it counts since I wrote that, but it's correct.
Thanks, working on documenting a car and just wanted to make sure there were not other possibilities. Dotting the I's and crossing the T's..
