I had grabbed a AOD junkyard core about the time the donor engine was pulled. It was rebuilt on a 2nd hand favor/trade like the rest of the stuff. A leftover B&M ratchet shifter was bolted to to a 1/8 plate bracket, welded to the tunnel and the original hole closed with sheet metal. The engine needed valve cover and oil pan gaskets to replace the originals, it poured out when parked on a drivers side hill. Rear main seal leak was annoying but not bad enough pull it back apart. Oil filter is a short style half inch thread common on dirt track cars, its a parts store Renault something. Should have changed it before assembly, live and learn. I had a newer 3.0 aluminum toyota radiator in the 4runner already so I tried it out with a 16" pusher electric fan zip tied right on front where the AC condenser once lived. A cheap sunpro water temp gauge and on/off switch did the job. It cooled 2wd daily driving loads fine, so it stayed for the time being.
The original 85 rear drive shaft was cut and mated to a newer front toyota CV joint to handle the increased drive line angle. This required a triple drilled flange on the smaller 85 t-case. The front 2 inch in 1.5 inch square tube front had enough slip to still bolt up. Since shackles are up front the suspension droop arc does not pull the shaft apart. She drove smooth to 60 mph, mild vibrations to around 70 then it clears up again to 80 in the tires are okay. I drove it from NCSU to Charlotte for the summer 2008? in this state. Nothing pretty, but it all held together.
