You have a GMC Suburban. An even more rare species of 'burb. There are plenty of junks out there that someone has already screwed up. Buy one of those and beat the snot out of it. When you get a little older and wiser, go dig that 'burb out from where you hid it and enjoy it. Nothing wrong with putting on some vintage speed parts. Yuou ca keep the straight axle and have power steering. No problem with AC either. If it's as nice as you say it is, then leave it alone. By the way, did you happen to see what some "stock" Suburbans bring at Barrett-Jackson? 47 and 52K. I was there, I saw them. My burb will be nicer than those when it's done. That's not a brag, it's just to show you that your truck is valuable and can still be enjoyed in a more stock condition. Smitty, quite frankly, it turns my stomach when you say this, "I can't stop thinking about 350ci, flowmasters, big tires on back, rake." Tell you what, I've got some sh*tboxes hanging around that I'll trade you for your burb. What do you want for it?
