The center support bearing seized at about 91000 miles.
The stock bench seat that came in my truck has to be one of the most uncomfortable seats made! It's OK for short trips, but for long ones, things tend to get uncomfortable. Loads of leg room though!
The stock 3 speed manual transmission in my truck tends to bind up sometimes. Most times though, it's only a minor annoyance. Luckily it's an easy fix as well.
Original Steering wheel cracked underneath. CHECK THOROUGHLY!
One of the pluses about the 1967-1972 GM/Chevy trucks are that they are EASY to work on!
Saw a review at this site on a 1972 Chevy C/10, and the reviewer said that one of the weaknesses in these trucks is the coil spring rear suspension, and how they couldn't haul heavy loads. I would have to disagree! I have the 1/2 ton (1500) GM model (GM/Chevy trucks very similar) and this truck never fails to impress me on how much weight the truck can haul!
Overall, these trucks are very solid vehicles. Not much can go wrong, with a 2 ton block of metal! Parts on these vehicles almost seem crudely put together. Very basic. That's great though as it means easy to fix. To me, this is how a truck should be, a real hard worker. No frilly gadgets like power windows, door locks, leather seats, and all the doodads that are found on trucks these days! These trucks can haul loads no sweat.
If you intend to buy one of these trucks, LOOK FOR RUST! Rocker panels get hit hard on these trucks. Also look for cracks in the steering wheel. The original steering wheels tend to crack underneath. If the truck is in good shape, don't worry too much about rust, as there are still parts available for these trucks all over the place.
In ending, a good place to check out on the INTERNET as far as 1967-1972 GM/Chevy trucks for help, information, and all that you'd need to know before purchasing one, then head to http://64.246.42.114/vboard/ (message board - not my site)
You're right on regarding the hauling capacity. I have the 1967 C10 fleet side and I only use this truck for hauling. I do allot of landscaping and have hauled many dozens of loads of gravel, dirt, sand, rocks, boulders, mulch, and road base. I will pack this thing full of anything. I do however, love my original bench seat. The seat springs are like sitting on an old bed, which I find very comfortable.

I have a 1970 GMC 1500 instead of coilover it has rear leaf suspension and a 350 and TH350 (in place of 3-speed) I do have to admit that the bench seat isn't the most comfortable, but I still like it for crusing I like that a GMC has a stainless steel grille with dual head lights instead of a chevy grille I have took away and added a couple of parts, but it is still all GM all in all I would rather have a 67-72 than any other year of GM truck.
I recently bought a 1970 GMC LB from the original owners grandson. 292 6-cyl is new, the rest of the truck is original down to the sun baked Az. paint. It is a base model with exception of working factory A/C. I bought it to help with our up coming move. The only complaints I have so far are the steering column which is too long, have to drive with seat back all the way and really makes putting the clutch in harder. The radial tires made steering more difficult so I replaced them with 700x15 bias ply's. steers great now and gets better gas mileage. I'm old so I guess I like the old look also. I drive it daily and to work, so far very reliable. Jack lilzeke65@yahoo.com.
