May be we should pool our money here to produce a F22 and F24 cases. I for one do not care if it starts the car I use a auto parts store battery for that. I would love to have a F22 case to show the car with.
This has been my battle cry for years now but as stated, cost and 'the ends justifying the means' seems to to be the reasoning (really odd with millions of old 65-67 Mustangs out there)
FWIW, I just noticed NPD is now carrying a yellow cap topper for the 24F battery. (Better, right)
(BTW, my OCD has been digging me everytime somebody calls these batteries a "F24" ~geese!)
https://www.npdlink.com/store/products/cover_sta_ful_battery_yellow_cap_and-208031-1.htmlAt this time, using a battery heat shield with a topper seems to be closest available option to an "at a glance" correct look of what the hobby is seeking.
Perhaps a vendor's supplier company could take this "Topper" and the topper for the 68-up version that has been around for years now, and design a lower half of the case with an open top that in conjunction with the topper (with functioning posts), a smaller side-post battery could be used inside . It seems that a percentage of the mold work has now already been done.
