68Timber is correct - there are no interchange parts between the Blazer/Jimmy tailgate and a Suburban tailgate. This has always surprised me given the General's clear intent to maintain a common parts bin on other items even between the trucks and the other divisions like Buick.

None of the major and interesting parts interchange, including things such as the gate shell itself, the glass, the channels and sash, the regulator, or even the electric motor. Oddly I think the Suburban motor MIGHT by common to the big B-body wagons, but I may be remembering this incorrectly. Either way I'd love to know the story from the either the design studio or the engineering office on how the Blazer & Suburban gates were allowed to take such different paths. It seems so unlike the General of the early 70's.
