hey i bought this truck and have slowly and painfully found out more and more about this truck as i go along. so i know now for a fact it is a 230 ci with a 1 barrell carberator but ive been reading that carb rebuilds just seem to always go wrong with the 1 barrell. i just had one done. is it a waste of money or right path? the rims that are on it are 6 lug and my new rims are 5 lug. were they origionally 5 to begin with or 6 cause it seems like i see alot more 5 lug patterns in this particular year. is there anything else you can tell me about my truck that i may need to know. problems that are typical of this year?
