Ive found various places that I can buy a used rear diff with 4.88s(from 90s runners w v6) for my 87 runner. The problem is that they want 300 or more for them. I was thinking that for that much money couldnt I just pull mine out of my truck and have it rebuilt with new gears and parts for a little more than 300? Also I was wondering if I buy a G144 diff from say a 95 4runner with ABS brakes will i be able to mount that on my 87 4 cylinder 4runner(Are the abs brakes an issue). And if so will i have to buy any other parts in order to mount the used diff like a gasket kit or something. Ive even found diffs for sale in Denver, my home, on carparts.com but they want at least 300. The guy sais its because the G144 is "rare". There was sure enough of them on the internet...
