I bought these door locks a week ago. I recieved it today and removed the original door lock and realized that they are not the same.

The original door lock, has an L shape compare to this new one.

Is there any thread of how to modify this lock?

Thanks

sorry for the bad urls. Fixed. Thanks

That looks like a different part for another model. Did you get a part number?

nope. i bought this before noticing that the stock ones look different. but the title says in ebay that this is for any 240 260 280z.

i am thinking of cutting the L shape on the old one and weld it on the new one.

I presume these are "Great More" locks. I had the same problem when I replaced mine. I had ordered my locks before cracking open the door to remove the old ones. (Of course!) I did tell the seller that the arm configuration didn't fit my '78, but I doubt that impacted the claim that it fits all S30 Z's.

Anyway, your solution sounds better than mine; however, if you or anyone else is interested in my not-so-pretty solution, I simply beat/bent a piece of steel around the arm of the lock, punching a dimple into the steel over the hold in the arm, to keep the extension from slipping off. I then bent the extended arm and fashioned a "finger" to slip into the square hole on the lock. It's not pretty, but it works just fine, and it's also easy.

The lock actuation levers that attach to the back of the lock cylinders are different in the 77-78 doors than in the earlier doors. Look on the back of the cylinder and see if you can interchange the arms. The early ones have a little clip that holds it on. Many locksmiths can re-work your original cylinders to repair them if they are simply worn. Good luck! Jim

I may try this idea. The seller is located in Singapore. I don't wanna pay for return.

Yeah they are way different. the teeth that moves the L shaped plate is broken and I don't think the locksmith can still fix it.

I will take pics later on.

All I can do now is I can still lock both doors but cannot unlock it. All I did is just unlock the hatch and crawl inside to open the door lock for now. .

How did your solution work out for the long run? I'd like to put the doors back together before the car comes out of the barn...

Do you have a photo of the finished lock? Also, is the new key anything like the Datsun key? I'd like to stay with the one key, but I could probably attach the door key to the ignition key so you don't have to go fumbling for keys twice to start the car. :classic:
