Trunk Lock repair manual

[Yennes]

Hi FBBO,

I recently restored the trunk lock latch for a 1968-70 B-Body and possibly other models as well. I wanted to share the process in case someone finds it useful in the future.

I completely disassembled the latch, zinc-plated the steel parts, and reassembled everything. However, keep in mind that the piece where the bar will be connected to the lock is made of aluminum and cannot be zinc-plated. Instead, I sandblasted that part, and it turned out great.

If you have questions do not mind to ask. I can provide the measurements of the rivets as well.

Below are some pictures showing how the latch is reassembled:

How do you do the rivets ??

I created a technical drawing of the original rivets, capturing as many of the original measurements as possible. I then gave the drawing to a friend, who machined them on a lathe for me.

Here are the old and new rivets.

How do you peen them in place?

I took a chisel, sharpened it on a grinding belt, held it against the rivet, and struck it with a hammer. I hit each notch twice, and everything was secure. Of course, you also need to fix the part in place.

Yes but the prices are ok I would say. If I would ship this size it would around $20. I think that is ok?

Reproduction units are $75. versus your refurb charge plus $20 each way shipping and long turnaround time. Hmmm! Don't quit your job just yet !!

Well, it wasn’t intended as a way to promote my services. I just wanted to demonstrate how the mechanism works in case someone wants to repair their own. Additionally, I would provide the technical drawing so that custom rivets could be made.

Nice stuff but when prices get involved, the thread turns into a sale thread? Yennes can probably help the ones that live on his side of the 'pond' and yet let us on the other side to see some incite on the procedure......let's not turn this into an ad. Thanks.
