Buick Parts enquiry from Australia.

[38HAULR]

I have just taken possession of a 62 Buick Special Convertible,and I am looking for suitable supplier for Buick repro bits if such exists,or a scource for secondhand bits.    This Buick has a busted locking/latch mechanism on the RH side to lock the top to the windshield frame, I imagine this item is common to the Skylark of the same year,and possibly would be generic to other surrounding years/models.  Any info appreciated, thanks.   Frank.
