james j neiweem Posted August 7, 2017 Share Posted August 7, 2017 Nice. Galvanized cab to boot. When did the galvanized cab start? 1987? Quote Link to comment https://www.bigmacktrucks.com/topic/50705-1989-mack-r-688st/#findComment-376871 Share on other sites More sharing options...

j hancock Posted August 8, 2017 Author Share Posted August 8, 2017 That's for sure! A surviving F model is a rare piece. Thinking about it a little more but I believe some items were galvanized on the R model before 84/85 such as the doors. 84/85 is when the whole cab was done.

Other than sanding the paint off to a thin layer of zinc, I can't say a galvanized cab has any other tells? Only speculating, but I would imagine that Sheller Globe built the cabs then used electrogalvanizing and then used a primer/sealer before shipping them to Mack to be painted.
