im planning on puting a 5l in a 84 rx7. i found one out of a 86 f 150, i can get the whole truck and plan to use the tranny out of the truck as well. anyone know if the tranny out of the truck will fit in just as well as one out of a mustang?

 

as long as the truck is a 2wd, there shouldnt be much of a size difference between it and a tranny from a mustang

 

laso with the weight difference between the 5l and the 12a am i going to need to beef up the suspension and or breaks?
