Hi, i'm restoring a '79 P125x and it has what i assume is an era correct BBQ rack with the sliding backrest, with the zippered bag on the back of the backrest with "Vespa" embossed on it.
The two bolts that keep the backrest from sliding backwards and forwards... I have the two bolts that are clipped or ground down to remove one side of the top. I purchase two plastic wingnuts. But from what i can gather, there was some angled sleeve that goes on the bolt and inside that would squeeze on the backrest bar. I've tried a few things, but can't get anything to work.
Does anyone have any info on what they are, what the look like, photos, can the be purchased, etc.?

Thanks!

I used to have one but it's been a few years and I don't remember, exactly how it works.

If you can post a picture of what you have it might jog my memory.

I sort of remember a piece of black rubber maybe fuel line inserted onto the carriage bolt from the bottom. When the wing nut is tensioned it squeezes the rubber and applies pressure on the backrest slide. I think the hole on the bottom of the rack is larger to accommodate the squeeze tube.

I believe I have said bolts with the wingnuts of unobtanium taped onto one of my bbq racks and will dig them out and take a pic after work.

Your description of the BBQ rack matches mine. Here are pictures of my hardware. I believe it to be correct as my BBQ Rack is minty Fresh! I hope this helps you!

Well I guess mine is incomplete or bodged

One bolt is longer and one is cut and shorter. Spacer and wingnut, no black bits.

Still hard to find these still attached. I have 3 bbq racks and only this one set

Thanks all! That is exactly what i was looking for. I have no idea where i'll find those spacer things, but at least i know what they look like now. I'll post if i figure anything out.
Thanks again for everyone's help!

Interesting don't think I've seen the metal bushings before seems easy enough to fabricate a piece of rubber might work as well. I believe the carriage bolt with the one side shaved off is correct so it can clear the outer bar and the square can drop in. The plastic wing nut is probably an improved addition.

Hibbert,

My observations of the differences between what you pictured and mine.

My carriage bolts are metric and have smaller diameter heads and do not contact any of the BBQ framework. So no need to shave them down. Yours may not be metric? In addition my carriage bolts are not threaded all the way like yours and are the same length.

I recall a guy selling these tapered bushings in the for sale forum. He had some machined and had extras.

Hec In Omaha ,
Do those bushings go in the orientation you have them in the pic, or upside down? I assumed they inserted from the bottom and the angled portion tightens up on the inner rack as the nut is tightened?

Here is a better picture before disassembly. I believe the tapered end points up. The diameter of the bushing closely matches the diameter of my wing nut base. I can't see the taper in the picture.

honestly it looks decently easy.

a couple carriage bolts from home depot, and use a regular wing nut instead of the plastic deal. the spacers would be easy to fab on a lathe if you had some measurements from one of the guys here. it's just cut some bar stock to the right diameter, drill a hole in it, and add a taper.

i don't have a lathe but there are lots of folks on here who do....

Here's what i came up with. I 3D printed them, and i still may pursue doing them in metal. They do tighten up the sliding backrest, but they don't release easily...i'm thinking that's due to plastic.
For future reference, they're 11.5mm long, 6.5mm diameter hole, 12.5mm outer diameter, and a 45deg chamfer.

Thanks for all the posts and photos!
