farmer52 Posted 21 hours ago Share Posted 21 hours ago What are the differences in a pre1993 CH cab versus a 1993+ cab? Looking at the 2008 Mack Accessory Catalog, several items show "93+". Also what is "keystone" versus "pre-keystone"? What year did Mack stop using fiberglass doors on the CH?

BottleHauler84 Posted 19 hours ago Share Posted 19 hours ago Thats a good question. Also, and maybe you know the answer, but I've heard the CH doors are not compatible a MH. Any idea if thats true or not? Quote Link to comment https://www.bigmacktrucks.com/topic/76193-ch-cab-differences/#findComment-586290 Share on other sites More sharing options...
Popular Post fjh Posted 5 hours ago Popular Post Share Posted 5 hours ago Im not sure of the answer to this But its my theory that they had a whole bunch of doors to use up when they quit building MH cab over and this is why they designed the CH to accept the MH door in the begging I and I don't remember what year the door became metal! ! As for the cab it was extended by 4 inches behind the door at one point so I cant be time specific on that! 2 1 Quote Link to comment https://www.bigmacktrucks.com/topic/76193-ch-cab-differences/#findComment-586313 Share on other sites More sharing options...

Not to hijack the thread here, but you're saying the MH and CH doors WILL interchange you think? I've often wondered about that and I never actually tried it for myself to know for sure.

The doors went to metal At one point how ever I did not pay attention as to the year! The earlier Ch doors were identical to the MH right down to the hinge mounting!

I always knew the fiberglass doors from CH and MH looked the same, but always wondered if there were small differences that would cause fitment issues.

In the direction of where they were heading ! Look no further than the change over of e6 2valve to 4 valve they changed the front cover on the 4 valve to the very similar e7 mounting shortly before the e7 was introduced! I could point out dozens of instances of this as time went on It was kind of neat to watch thinking back on it! 2 Quote Link to comment https://www.bigmacktrucks.com/topic/76193-ch-cab-differences/#findComment-586328 Share on other sites More sharing options...

The doors on the MD look about the same. I never really paid much attention because I just assumed it was a totally new designed cab from the look of the hood. The company im leased on to has a few MD company trucks. Ill have to look them over a little closer now lol. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/76193-ch-cab-differences/#findComment-586329 Share on other sites More sharing options...
