Rear 3 point Seatbelt conversion for Mk1 Golf Convertible.

Hello All, Just wanted some advice about who/where I might get a rear 3point seatbelt conversion done? CrazyQuiff is trying to charge silly money for them.......ideas?

Find a breakers in the states that is prepared to cut them out of an original car and ship them over.

Crazy is not the cheapest, but for things like this you get a well made and fit for purpose piece of kit that is safety critical.
