Quoting mitsuturbo:
You're going to sweat, bleed and maybe even cry if you own a GVR4 for long. Make sure you have screwdrivers, prybars, 8, 10, 12, 14, 17, 19, 21, 24, 27, 32 and 36mm sockets and wrenches, and it wouldn't hurt to have 11, 13, 15 and 18mm as well, in case someone's replaced some bolts on the car with nonstandard sh*t somewhere.
If you do ALL your own work, at some point you'll need snap ring pliers, micrometer, dial indicator, good torque wrench, pickle fork, and possibly a press and bearing splitters. EVERYTHING needs work on these cars, being as old as they are, and it's usually hundreds of dollars cheaper to do it yourself.
hey MT, you forgot one very vital tool: the BFH /ubbthreads/images/graemlins/grin.gif other than that, i'd say you hit it all right on the head.
OP: good luck with your new venture!
