Are any of these parts valuable? 83 Mondial Cab

Those were probably taken off because they were worn, but by now they may be useful.

In the 3rd picture, I think one of the boots on the left is for the clutch slave cylinder. Any rubber items that old are prone to tearing and I'm not sure how available those are, so it would possibly be of value to someone that needs one. When I had my slave cylinder re-built they put a new boot on, but I had the old one that I hadn't given them. It fit a lot better.

The brake booster might be rebuildable, so someone might want that to have rebuilt then do a swap, rather than pulling theirs out and waiting.

 

They are rare but they need to be in usable condition, the nuts can be so corroded that they would not be usable.

 

I don't think I see anything of notable value.

The brake pads look like plenty of wear left, and they have the OEM style wear sensor wires. Could be useful to a handyman or reseller who has worn pads and doesn't get fussed about needing new.

The brake lines might have fittings that can be salvaged for a brake line rebuild, but since new lines are available, albeit without the original style fittings, probably not much immediate use. The oil hose fittings might also be useful for a line rebuild, new hoses are not readily available.

The shock top mounts might be usable. The other suspension parts would likely be too worn to bother using given the labour involved to replace those types of things.

Maybe in the future when there are concours restorations of these cars some of the old parts would be scarce and rebuildable and find a market. eg. perhaps the engine mounts could be rebuilt? The brake boosters are usually rebuildable.

I would just put the stuff in a box, label it, and let it sit for 20 years. Like many of the boxes of used bits in my workshop...waiting for the moment when Mondial's become coveted and restored like eg. Dino's!

 

Oil hose end fittings,, and the one slightly used ring nut.

 

Rubber Oil lines (from oil cooler, brake lines or others) you cannot use them again once air is touching the rubber inside. Rubber swollow up and new oil will degenerate and take it apart.
