Seat back release lever

Hello again. We've noticed that the seat back release levers on our '84 spider are missing, as is the entire mechanism. Meaning that the seats just fold forward without needing to release them. Probably a bit of a safety problem. Anyway, I have not been able to located a replacement part, or much discussion of these mechanisms on Spiders - I imagine they don't fail very often. Does anyone have a source for these parts, or even a diagram of the components, so that I could figure out what exactly is missing? I am still a number of posts short before I can post pictures, but I will get some up as soon as I can. Thanks!

Might be something to get used from Alfa Parts Exchange in California.

Thanks - I'll give them a call as soon as I know exactly what to ask for. Obviously the seat hinge is intact, but there doesn't appear to be any remnants of the locking/latching mechanism. Has anyone ever taken one apart, or found a diagram?

There is not a lot to them, took mine apart when I recovered my seats. Just hexagonal rod, a hooked latch, handle, and spring, if a recall correctly. I bet the CarDisc manual has an exploded view... I will check it out, I am almost home....

maybe someone replaced the latched exterior hinges with unlatched interior hinges?

I found the parts on the CarDisc but they do not list the individual parts, only the entire mechanism. That makes me assume that the individual pieces are not available unless possibly at a Pick and Pull or something. I would have posted a screenshot of the shop manual page but I could not figure it out....

yeah the latched hinges are welded together from what i remember. i dont think you're going to be able to replace the latch mechanism. i'd start looking for the hinge/bracket

Yep, found these on eBay this morning... seems that $90 is about the going rate. Will have to call the local junk yard and see if they have any spiders.

Just got my post count up, but unfortunately forgot to get a picture of the hinge. Will grab one this weekend. Here's a photo of the car in the mean time :-)

Yes! Specifically the seat is missing the lever and the hook, as far as I recall. Not sure how that came to be, but we will probably disassemble them this weekend and see what may have transpired.

So here is what we have... The latching hinge may very well have been replaced with an interior non-latching one, but I can't tell for sure. The seats have been removed at some point, as there is "new" hardware attaching them to the floor (another thing to replace). Did these seats ever come without latching hinges?

your hinges look a bit of a mish mash.

more like GTV seat release levers (w/o the lever or the hook, and with some odd bolts that are not factory) in the hammered gray look.

Remember, for any hinge to work your seats need the metal bit sticking out (circled in red), which, if my memory serves me, is part of the seat pan itself on a spider.

I can't see that in your photos above....has it snapped off maybe or been hacksawed off or something?

It is possible that the inside hinge of the opposite seat has been placed on the outside seat. Only the outside hinge has a latching mechanism. The 67 Spider did not have a latching mechanism but used a plastic catch that held the outside of the seat hinge. These failed quite frequently and only in the past few years has there been a repo substitute. Since you mention that the seat mounting is incorrect you may want to check that you have the right seat pan. If the round pin were missing, that side of the seat would sag as the pin is also the travel stop. The 67 Spider has a flat plate as the travel stop.
I have a box full of S3 hinges if you have that need.
Cheers, jon
