Car and truck, totally different, maybe if the length was close you could fab it in, but I'm sure you'd have to use the truck wheels as the bolt pattern probably wouldn't be the same...So I came upon a rearend (POSI) from a 63 C-10 anyway to make this work for my 63 Impala , can the pumpkins swap with the mods to my case . Or am I out of luck to get to use this ?
