Let's try this again. Looking to add three point belts to the rear of my '85 3.2
 

I have the belts themselves. The rear deck cover with the proper fittings has been harder to source.

Can anyone point me in the right direction?

no but subscribed.

Is this the one you are looking for?

I just ordered some plastic covers for the rear seat belt outlet from a Volvo on Ebay for $14 and plan on just cutting the hole in my existing rear deck to fit it.

I couldn't find an outlet cover I liked by searching for Porsche, but there's tons of stuff under every other car manufacturer.

I was thinking of that. Volvo, huh? Which ones?

That could work...

The first link does not look like a 964 deck. 964 should look like the one in the link below. FWIW I added belts to my 86. The anchors were already installed so the belts bolted right in. I bought a set of 964 rosettes and cut my existing deck. J

Did you just throw the plastic pieces at it, or did you painstakingly measure? And if you did measure, would you happen to have retained the measurements?

I'm sorry, it was from a 924, not a Volvo. I looked at the Volvo first and then found the ones for a 924 for $6 on Ebay.

I am not installing a retractor, however, so all I have to do is bolt the three points which makes it a lot easier to fool with. I'll post a thread on it when I get it done (if it works)

Used a 964 shelf as template and used the plastic pieces from the 964 shelf. The belts are from a 964 as well.

No measurements. It's been a few years but, at the time I couldn't get any traction on measurements so I ended up going with the Mark I eyeball. -J

How about a photo?

+1

The 924 plastic parts would probably work, but I think the 964 parts are probably the better choice. I think I have 964 belts and retractors.
