how much bombing?
college cummins,
when i was in your position - buying a 1st gen for the first time - i didn't know jack. the only reason i ended up with an auto was because it was the nicest one around. all the trucks for sale with sticks were junk. so, i went with what was out there and i like it! normally, i am not an auto guy. all my life, my trucks or cars have been sticks (unless it was just a beater that i didn't care about). almost all of my driving is on the highway, so the auto is just fine... sit back and relax! sure the sticks are fun, and i miss it sometimes. so what? most folks i know with bombed 1st gens have autos, typically handled by dtt. mind you, i live in the land of pdr and dtt, so there are more of us around.
anyway, i know it may be a hard question to answer, but think about how much power you might realistically want down the road.
here's my two cents...
if you're going to keep it stock or mild bombing, then an a518 or getrag... your choice. you may experience problems with either, or maybe not.
if you are going to moderate bombing, then an a518 with new torque convertor, valve body, fluid pan, etc. or swap out the getrag for a newer NV 5 or 6 speed and beefy clutch. both options will hurt your wallet big time.
if you're going all out, then an automatic is the way to go since you can beef it up to take anything. and, since your going all out, no need to watch the bank account. :-laf
again, just my two cents. it's all i have left!
cheers,
roy
