Well, as a lot of repop parts, there are good ones, and then there are the ones they make.
The 22F battery I use right now is a later 68/69 original case one. To me, this is at least closer to what came in my car (early 1967 GT 350), yet, the only acceptable battery is the red capped group 27 battery which also requires you to replace the battery tray. I supposed this is because that is what the rules say (MCA).
And, if you look on Ebay, there are plenty of battery tops, incorrect and still only later (68 on up) red capper Autolite group 27 the the rules specifically state points off. You'd think somebody would try to even make a group 22 battery top, but, not just yet.
