interchangeable parts 79 & 83

[poorboy411]

are 78-79 blazer parts interchangable with 83 far as interior-seats-panels.ect... and top

 

[R72K5]

door panels no, although are large style, you would have to change door handles and such 77-80 are wide style door handles, other things different too, not hard to convert,

and i know in the pickups the area udner the seats changed height in 81, btu dunno in k5's

good luck
