I was think of picking up a 36R but it might be close on the width. What battery size are you running in your Maverick or Comet?
I think that Group 24F battery was virtually the standard for Fords of the era. I know it's what was used in my 1968 Cougar, my 1969 Cougar, my 1970 Galaxie 500, and my 1974 LTD.
Thanks for all the input. I purchased a Motomaster 24F from Canadian Tire. I found however, the dimensions were 9-15/16 “ long by 6-5/8” wide by 8 “ high. I measured it up at the store and it is identical to a 24 they had on the shelf. Looks like Motomaster is consolidating sizes and the size is slightly smaller than this chart I found. The battery was made in the USA but I couldn’t tell which supplier it is.
