When I removed the in-cab tank from my '71, I replaced it with a late-70's C-body tank. It fit perfectly between the rails in the spare-tire area, with the filler behind the plate. I don't remember the size, but it was about double the in-cab, and I'm sure it would be significantly bigger than that Mustang tank.
i was trying to remember that when this topic was posted, and you remembered it for me ! thank you sir !
if i remember correctly, [there's that "remember" thing again
] the 74-78 C-bodies i owned over my lifetime were somewhere around 22-26ish gallon tanks ?
mustang tanks are maybe 15ish [?] and in cab truck tanks are maybe 14ish ?
just an old guy who knew many things years ago, but has forgotten lots due to the spiders hiding the knowledge in his noggin with cobwebs...............
