I've got a couple trucks, i Pulled the l43 out of the 80, and it was jacked up when the clutch plate grenaded.

So i pulled the trans out of the 84, which should be a g52 (which is not the best, but better than the l43)

When i put the 84 back into the 80, if I use the 84 trans cross member, will it bolt up in the right position on teh 84 frame,
or will i have to make mods.

if so what kinds of mods.

Also any other gotchas to look for? do i need the speedo cable extensions? Reverse switch? 4wd switch?

I'm assuming I'll need to cut the floor.

bought 84 clutch master/slave to swap in. as that was reccomended.

Thanks,

Eric-
 
It sounds to me like you have both transmissions out of both trucks?
Set both transmissions beside each other and you will know for sure.

Speedo: Nope, should be the same. It's on the transfercase, and both cases are, more or less, the same.
Reverse switch: Nope, keep the switch on the G62. It's a simple on/off switch. If the connector is different, then swap.
4WD switch: Nope, they both should be the same.
