[DeTomaso] Techno question: stock rear brake shims

[Julian Kift]

They would be a fairly easy part to take to a local shop and get a bunch laser cut, you'd have thought a vendor would have been all over this as the lock tabs are a consumable that weakens after a couple uses and the tab breaks off. The caliper bolt spacing isn't that uncommon of the era, surely someone must sell equivalent lock tabs that don't come in a De Tomaso plastic bag....?

Alternatively one could drill the bolt heads for safety wiring, or purchase pre-drilled bolts. The second option may be more expensive than new lock tabs in the short term, but almost infinitely reusable.

Chuck,

Two things:

1). Front and rear caliper bolt spacing is different. You can't put a front anything on the rear.

2). Rear calipers don't have shims. :)

Both front and rear have locking tabs which go immediately underneath the head of the mounting bolts, but they are not shims. They have tabs which are bent up to prevent bolt rotation. Front calipers also have shims between caliper and upright which spaces the caliper inboard by the thickness of the shim.

The caliper locking tabs for the GT5 (which has different calipers with different bolt spacing for the different spindles/rear uprights) are very cheap. However the ones for the early cars are obscenely expensive for what they are.

Look at Wilkinson's website for exploded drawings and associated parts descriptions with eye-watering prices for the locking tabs....
