My lock cylinders are pretty worn, often it's hard to get the key in.
I been looking up lock cylinder replacements (E-bay, Junkyrd, new...)
I keep finding ones that 'Don't fit your vehicle', or whatever (almost all look like they will fit- except 1)
My locks are black, not chrome on the outside, I'd like to keep that.
Since I have 2 keys anyway (doors & Ign), I think I'd like to use a newer style key, maybe the double-sided teeth early 1990s? - Anyone know about the differences, & potential probs?
I don't mind a reasonable bit of modification, but don't want to get too carried away... e.g. welding, then have to repaint entire door.

Not to point out the obvious, but have you tried shooting some WD40 in the lock cylinder? You would be surprised how much that can help sometimes. Those tumblers and mechanisms tend to get gummed up over time

It's not a direct swap, i put all of the locks from my 91 donor on mine (85). The rear latch is the only lock that is same, the door locks have a smaller bezel but will clip in the same way leaving small gaps around the edge. You will have to modify the linkage that hooks the cylinder to the latch. It took me about 3 hours to do driver, passenger, and rear hatch.

I lube it regularly.
That's not the problem, The insides are very worn and the flat piece of metal in the center will float to the side, so I have to fumble with it to get the key in.
At night I suspect this may look like a drunk who can't unlock the door.... I don't need any hassles

- Yeah I should call one and ask
I went into a place a while back, asked him how much to upgrade to newer locks/keys ... He said he couldn't do it ..!?
I said "you Can't?" - I left.

I tried to buy some new locks for my 88 and nobody has them. I even tried the dealer, they said it was a special order from some place in WIsconsin. At $58 each I decided to deal with it for now.

So, How much gap? will it move if you try to twist it?
Maybe a little JB Weld in the gap will solve the problem?

Just have a tough time finding the right ones. Esp locks with the Black coated face outside (like my original ones)
Maybe I need to go to the junkyard and see what they have

They stay solid, just a look little out of place. I tried to change the trim and use the old lock parts, but no go. I'll snap a picture tomorrow and post it here. It's nothing horrible i just live with it because it's so nice to have one key fit everything.

I've already replaced my ignition cylinder and tomorrow will be replacing the ignition switch. I am just happy to have the doors and hatch with the same key. I am going to swap the passenger and driver door locks so at least I can get in without a fight.
