It's not a difficult swap, its all just bolt in stuff like trans, axles, shift rod etc and the engine needs a manual flywheel and oil pump fitted and remove all the uneeded crap like servo, oil tanks and lines etc
All semi auto are IRS so it doesnt make any difference there concerning the axles.
The only hard part is if the car doesnt have a clutch cable tube.
You get lucky on most 70s semi autos, they tend to have them but the early 1500s didnt.
Cutting open the tunnel and welding in the tube is a horrible job
Just lift the inspection panel under the rear seat where the coupler is, you will be able to see there if it has an unused clutch cable tube
