Yeah, It's right, the C15 is a 1/2 ton truck, GMDAD my truck is almost like yours , only that I have a 4 speed tranny, I want in the future to put a 5 speed because I travel a lot, my truck have chevy 90's seats and you're right they are more comfortable, my truck its the first thing that i Got with my efforts and for that reason I love It, So it needs to renew with a Fresh 292 power monster, I will put in the future some pics of she, Yesterday I have a discussion with a mechanic that criticize me of the useless spends of money to my 292, he tolds me the natural conversion to a 350 v8, I dont know if Im nutz but I really appreciate that inline six..
