New Member, 1972 GMC 2500, Purchased New By My Grandparents
Greetings--
*First Post* As of last Friday, I'm the proud new owner of my late grandparent's (91 and 99 years old) '72 GMC 2500 Custom, purchased new in March '72. I've been fond of it since I was a kid and always thought it would be great to own someday. 350/4bbl, automatic, PS/PB, factory air, original split rims, original paperwork still in the glovebox with Protect-O-Plate. It's not perfect by any means as it was a daily driver before being partially restored in 1988...and yes, the running boards have been taken off as of last night. ![]() I do have a few questions. 1) Door locks work well except I am unable to lock the driver's side door with they key. It unlocks with the key just fine. I wanted to hold off on popping the inner door panel off to look at the mechanism until I talked to the experts. 2) Oil recommendations? I'm a Shell Rotella fan and run that in my '93 Land Cruiser (ih8mud.com member ![]() 3) Transmission fluid recommendations? I don't think I'll flush a 38-year-old trans, just change the fluid/filter. Again, throw your recommendations on me. 4) Should I get the split rims off of it? I know they can be dangerous but I believe that is just while they are being aired up. How dangerous are they to drive on? 5) Pretty hefty rear main leak. How difficult to change? I'm sure I'd have to lift the engine a bit. Pics from last Friday below. That's their '91 Lincoln with only 15,000 miles behind it. ![]() ![]() ![]() ![]() ![]() ![]() ![]()

Re: New Member, 1972 GMC 2500, Purchased New By My Grandparents
Welcome to the forum from Southeast Missouri. Great looking truck with a lot of history.
Split rims are not a problem to drive on. A lot of tire shops hesitate to deal with them. I had a '72 GMC with standard 16.5 rims so you may be able to find them pretty easy if you want to change. I am sure others will chime in with more info.

Re: New Member, 1972 GMC 2500, Purchased New By My Grandparents
My door lock acts the same way. The locking mechanism is probably just a bit worn out. See if you can push on the door as you lock it and see if it locks a bit easier. If it does not then you might have to replace the locking mechanism.
I like Shell Rotella. 10w-40 or 15w-40 is good. I would stick with dino. I have a Valvoline transmission oil in my truck. You can change the rear main seal with the engine in the truck...it is a real pain to do though. The truck looks really nice!!!! Last edited by Alex Hayley; 12-07-2010 at 11:16 AM. |

Re: New Member, 1972 GMC 2500, Purchased New By My Grandparents
What a pretty truck ..And I'm going to say thanks to the grandparents for taking care of it so well.. You got to be having heart flitters owning this right now ..right? LOL
If you want to keep it stock the split rims will do just fine ,,just be sure and have some one with the proper tools and know how to fix a flat if you have one.. If you change to some up to date rims ,,then just keep the old ones for sentimental reasons if you like ,,as lots of us on here update the rims ... welcome to the board and keep us up to date on the truck Gp Larry from Oregon |

I do have a few questions.

I wanted to hold off on popping the inner door panel off to look at the mechanism until I talked to the experts. 2) Oil recommendations? I'm a Shell Rotella fan and run that in my '93 Land Cruiser (ih8mud.com member ). Your thoughts on weight? Synthetic/Dino? I'd prefer to run the same weight all year. Here is a recent link... http://67-72chevytrucks.com/vboard/s...d.php?t=434150 3) Transmission fluid recommendations? I don't think I'll flush a 38-year-old trans, just change the fluid/filter. Again, throw your recommendations on me. 4) Should I get the split rims off of it? I know they can be dangerous but I believe that is just while they are being aired up. How dangerous are they to drive on? Some folks have replaced these as some have said...safety when changing tires. But that is your call. 5) Pretty hefty rear main leak. How difficult to change? I'm sure I'd have to lift the engine a bit. Great looking truck and ![]() ![]() ![]() ![]() ![]()

Re: New Member, 1972 GMC 2500, Purchased New By My Grandparents
Welcome to the board from the left coast - that's a beautiful survivor you have there. Personally I wouldn't worry about the rims/tires until you need to change the tires out, then switch to a one piece rim. The lock is an easy fix and there are lots of aftermarket parts available, but try the pushing on the door trick, that's what I have to do to my '67 sometimes. That's an interesting color combination in the cab with the grey; I've never seen that before.

Re: New Member, 1972 GMC 2500, Purchased New By My Grandparents
Welcome, and congrats on your new truck! Very special indeed to inherit one in such great condition, and better still with the family history / sentimental value.
1) Not sure, but I would try shooting a bit of spray lube into the lock and work the key back & forth first. You might get lucky. 2) Opinions are all over the map -- I use 10W30 dino. There's a recent thread somewhere about engine oils. 4) I agree with Shyguy... no problems but many shops won't touch 'em for safety reasons (lack of training & experience). Truck tire shops would be your best bet if you decide to keep them. Best bet might be to change to 16" wheels.

On the door lock do as others have suggested, give the door a slight push inward as you turn the key in the lock.

Re: New Member, 1972 GMC 2500, Purchased New By My Grandparents
Welcome. You have an original beauty there that is really special. When you have one that original, you need to keep it original (just my opinion - it's your truck). That was a pretty loaded up truck when your Grandpa bought it and it has certainly been well taken care of. Congrats.

It will stay original. I may debate removing the split rims at some point but they will not be sold.

WELCOME to the board,... I was at that sale long enough to drive by and look at it. (I was afraid to stop,... because I would have been bidding against you. Ha) I had seen it before in Mexico, MO. (My home town) I'm glad someone in the family got it. This is a great site for all kinds of info and PLENTY of helpful people. Again,... welcome to the board and CONGRATS on your new truck purchase. That's a beautiful truck you have.
