1992 4runner 4wd trouble

I recently bought a 1992 4runner to buy fix and flip, the only thing holding me up is the 4 wheel drive. It is a automatic and can shift in it but it doesnt actually shift into it, the hubs are good and my buddy said it might be the vacuum lines. does anyone have any input?

Also the A/C is out and needs to be recharged with R12, does anyone know how to convert over to the 134a or how to get their hands on R12

 

Sorry not to sure on the 4WD cause I haven't worked on any older than the Taco. Buy you can still get R12a to charge older A/C systems.

 

where can you purchase R12a, im in california and I cant find it anywhere

 

Unless you already own a vacuum pump and manifold gauge set. I would just drop it off at a local A/C shop to have the system vacuumed down and then charged. They'll likely have r12a. But you have to vacuum down the system and monitor the pressures as you charge. If there is air or water vaporbin their before you charge it work work well. Should change the receiver dryer too.

 

how much does that usually cost, I bought this to flip it and have already dropped almost 3G's in it

 

It varies, but I've seen people pay 125-200 for basic vacuum and fill.
