farmer52 Posted August 21, 2013 Share Posted August 21, 2013 I am sure this info is somewhere on this site but too lazy to search....First year for the R Plus cab?Is there a noticeable difference in leg room in the Plus cab?First year for the "plastic" dash in a R? Is the Plus cab a "direct" bolt up on an earlier R (mounts, steering, electrical, air, etc.)?Other improvements in the Plus cab versus earlier cab?Thanks for the info!

2stacksuperdog Posted August 21, 2013 Share Posted August 21, 2013 I would say 73 too but they kept using them up into the later 70s. Our 74 had the +3 cab and our 75 had the smaller one 1 Quote Matt Link to comment https://www.bigmacktrucks.com/topic/32400-r-plus-cab-questions/#findComment-200876 Share on other sites More sharing options...
Maddog13407 Posted August 21, 2013 Share Posted August 21, 2013 73 or so give or take a few months was the first year for the plastic dash. yes little more leg room because the seat goes back a little farther, BUT not far enough haha. and direct bolt up? not so much. need to change the front frame mounts, depends on steering and depends how the fuel tank/rear cab square tube is. I put a newer telescoping steering wheel and swing down clutch pedal with cable clutch in my 66 R model. was a pretty direct bolt up. holes were all there.

farmer52 Posted August 21, 2013 Author Share Posted August 21, 2013 Thanks for the information. I thought the plus cab started around 1973 but was unsure of other specifics. So if I want a R, I should be looking for a 1973 or newer? To recab a "rusty" pre-73 would require an early cab? I am not into repairing sheet metal.

Green Dash Posted August 21, 2013 Share Posted August 21, 2013 Your taller than I am and I felt a bit cramped in a green dash R model, although a newer steering wheel will do wonders for belly room if you have power steering. The later R cabs are galvanized but I'm not sure what year that started.

Maddog13407 Posted August 21, 2013 Share Posted August 21, 2013 its possible to recab an older R with the newer style cab but you need the front cab mount brackets for the frame as the older cabs has the biscuit mounts like a B model and the newer ones had the saddle type mounts like a Superdog. also might have to change the rear cab/frame mount depending on what fuel tank set you you have. out r model at work has the square tanks mounted like a B model. most R models were under slung tanks that hung off the square tube that went across for the cab mount. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/32400-r-plus-cab-questions/#findComment-200979 Share on other sites More sharing options...

farmer52 Posted August 21, 2013 Author Share Posted August 21, 2013 I think I will keep looking for a 1973 or newer R. Unless a pre-1973 is rust free and CHEAP! Of course a newer R will need to have the same credentials.

daveigou Posted August 22, 2013 Share Posted August 22, 2013 In 1987 Mack went to the all two sided galvanized steel cab, before that only certain parts were galvanized Quote See my Flickr photostream page http://www.flickr.com/photos/96692978@N05/ Link to comment https://www.bigmacktrucks.com/topic/32400-r-plus-cab-questions/#findComment-201011 Share on other sites More sharing options...
rsb502 Posted August 22, 2013 Share Posted August 22, 2013 the galvanized cab was a Macungie thing in the early trucks, my 84 was a Hayward truck and had no galvanizing, they tend to rust quicker for sure.

2stacksuperdog Posted August 22, 2013 Share Posted August 22, 2013 our 84 R has a galvanized perfect rust free cab. That's the main reason we bought it.
