I am finding it kind of hard to get a lower shifter boot for my ’72 Mach1 four-speed. It was originally an automatic but I converted it some time ago. I was trying to find the boot to complete the conversion but no luck. The only ones I can find are for the 64 through 68 Mustangs and I am starting to think the 69-73 didn’t have them. Did the 69-73 four-speeds have lower shifter boots?
