Does anyone know what years k5 blazer tops interchange? Am wondering how late a model will a top off of a 79 fit.

 

all half cab design fit all other half cabs. i have an 82 with a 90 top from a jimmy that fits exactly the same as the spare 82.

all full verticals will fit all verticals.

 

Yep, anything '76-'91 will interchange. The tops from the '73-'75 will interchange. For the 1st gens, you need a 1st gen top as the rear glass was hinged to the top.

 

So your saying a 79 will fit a 90?

I posted my second question before I read the second reply. So thanks for the info it is much appriciated.

 

i didn't know that about the 73-75. that's kinda neat . make it easy. no motors to move heavy rear windows


so if your top looks like this half cab design



it will swap


what year is your truck?

 

73-75 trucks were full convertibles with the 2nd gen body style. The window is in the tailgate like the '76-'91 models, but there was no power window option. I have both powered and manual tailgates for my '74 with many working spare parts for the electric window gate.

The '69-'72 K5 was the first generation and had a lift up rear window.
