Rear tail gate Balzer.

[eighteenninetytwo]

Local pick n Pull got a 78 blazer in recently. Two questions:
1. Are the internal components for rear window raising alignments etc identical to the 75 tailgate?
2. What tools would I need to take the whole tailgate off and bring it back with me?? Actually that raises a third question, I ASSUME but i'm not sure, that all american 1970's vehicles would use imperial measurements in terms of bolt head sizes etc am I right? (forgive the odd question please - I'm a recent immigrant from the UK and they went metric around then).
