how does the top bracket mount to the car window from on the vetn window? Is it srewed, bolted, threaded, riveted????

Easy to do? I don't seem to have any slots for it.

the top mount bracket for the 1/4 window on early models is screwed with 4 mm screws

and on the later 68 on windows its riveted to the 1/4 window outter frame

on the early models the screws always rust so there probally not there

the bracket that attaches to the actual 1/4 window frame is riveted

Alright, im getting all the bits sent out to me front second hand, so hopefully i will slot in ok. Ill get bak to you if i get confused with the bits.
