1973 Blazer Window regulator and channel

[manfromeastvan]

Hey everybody, I need a little help on the Blazer I'm trying to fix up. I need to change the driver's side window regulator and the channel that connects the regulator and the glass. I'm having no trouble finding reproduction 1973 regulators, but nobody has the channel. Some people have told me I can use a 1974 regulator and channel, but most everything I've read says that won't work. Any help on this would be a lifesaver, thanks.

as far as i know all the door parts from 73-80 are the same LMC says its 73-87 and they sell the channels page 16 of the new catalogue
on the 73 blazer they had the top that came off over the cab, as is 74 but those parts should interchange and so should the inside of the door pieces from pickup to blazer im using a pickup catalogue not a blazer one LMC makes a blazer catalogue too from 73-91
