hi everyone, ive been wanting a big truck to work on and go 4wheeling in. ive got an 02' trailblazer but theres no parts for it and i dont wanna tear her up off road. i want something with a pushrod, since i have no idea how to work on these new engines , and i want something big and tough. since im a GM guy i decided on an older blazer. i really like the models from the early 70's - mid 80's. but my problem is, i dont know many of the differences between the different models. i know id like to get one with the removable top, and i want to, make sure that when i find one i like i wont be getting a model that has some flaw that ill run into later on as i work on it. do any of you guys have any advice on deciding what to choose? im looking to get one cheap with little done to it already. i wont be going crazy with the build since id still like it to be manageable on the hardtop. any advice, info, links would be greatly appreciated. thanks David PS...im still searching the forums hoping to answer some of my own questions but im not finding what im looking for (but alot of sweet ideas for when i do get the truck). im might repost this in another forum here too if it looks like it might fit in.
