being a 79 does it have the 20r or the 22r...? because that could mean alot in the swap.

No difference in the shop weather it had a 20r/22r as long as the whole motor is being replaced....

As is it will have to be a 84-up block anyways to do the swap..

The position of the motor mounts are the same? For some reason I thought they were a little different.

i thought there was a difference in motor mounts, between the IFS, and straight axle rigs....

i know my adapter mounts are for an IFS rig, and i had to modify them to work on my 85.:eeek:

I haven't seen a set of aftermarket adapter/motormounts that didn't have to be modified in one way or another.... :;

Ive never had to modify any mounts on any of the swaps I have done.

when i swapped the 302 in my 85, i got a used adapter, and mounts. both used in an IFS yota.
the mount holes didnt line up, and i had to drill new ones an 1" or so further back.

I had to use the motor mounts from the 88 when I put it in my 81. Only the mounts on the block not the frame.

Thats a V8 swap for you. Nothing bolts in on those lol.

here is the plan

I plan to use the old harness for all the lights, and the heater. I will swap steering colume because the 2wd one i got don't have a u-joint and the wiring will match on that. Someone posted a link on here i can use to splice the gauges back together. The sending unit i will have to swap out nothin to that. It sould be easy the pull the efi harness through the engine bay to underneath the dash. The down side i will have two fuse boxes, put power to the old harness and clean that up. That is the plan if anyone a better plan or advice i would love to here it. I got the new harness out, the new truck dash is all takin apart.
