Rob Posted September 27, 2010 Share Posted September 27, 2010 I have a few R model cabs and am wondering how to tell the year of manufacture? All have the serial numbers intact on the riveted tags in the left door jamb.Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

Rob Posted September 27, 2010 Author Share Posted September 27, 2010 what about the id tag on the left door, or the other one on the correct drivers side, in engingin bay on firewall.GrantA couple of the cabs are just cabs without doors. I can't remember seeing tags on two of them on the firewall(s). Glad to hear you agree the correct driver's side being the left.Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

Greg Rider Posted September 27, 2010 Share Posted September 27, 2010 What the hell!!!!???? "Oh poor me, I have so many trucks I can't tell them apart! ","I can't tell one from the other","I don't know what I have". There is a huge part of me that feels no sympathy for you on that issue.

Mike Posted September 27, 2010 Share Posted September 27, 2010 Hey Rob, here is the R -Model I wanted ya to see. I could not find the thread to post it in the correct place. Please forgive me guys, i'll try and do better. This truck was at our Music City ATHS Show in Cookville, TN and I enjoyed talking to Jim the owner and his friend. I just had to show it. I also told him about the BMT site hoping he'll give it a try.mike Quote Link to comment https://www.bigmacktrucks.com/topic/15913-r-model-cab-year/#findComment-64374 Share on other sites More sharing options...
rhasler Posted September 27, 2010 Share Posted September 27, 2010 I did a bit of checking today and it seems that the number riveted to the door jamb doesn't mean much as far as Mack is concerned. For instance, if you were ordering a new cab the chassis serial number and GSO would be needed. We tried looking up major compnent serial numbers on a few different RD chassis but the cab serial didn't come up. It appears that the cab serial number is really only meaningful to the cab vendor. The parts manager said he thought the cab vendor was Mayflower or something along those lines. Quote "Mebbe I'm too ugly and stupid to give up!"

Rob Posted September 28, 2010 Author Share Posted September 28, 2010 Thanks for the research. Really doesn't matter much as to year but there are minor differences throughout. I've seen holes that are factory punched for the heating and air conditioning in different places in the firewall and ancillary mountings differing in placement also. I have a cab that is from a 1978 R686, and another from a 1975 R685 that differ from each other. Then I have a cab from the mid 1980's that has many holes factory punched, with plastic plugs installed into unused holes that are painted over with cab color.Thanks,Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.
