BOB DINGSDALE Posted December 31, 2012 Share Posted December 31, 2012 Stan Young Jr put a LJSW cab and fenders on a R and it looked beautiful.A fellow out here put a B-53 on a R but should have used a B-73 with longer front end.looked good though.will post pictures when get dug up..the B-53 was a used every day truck after the convertion.

alex g Posted December 31, 2012 Share Posted December 31, 2012 i saw advertisement in a old Overdrive mag where Mack used to sell R Model cabs and hoods to convert your B in to a R.Kind of like a reverse glider kit.It is not impossible to do but will probably make you have to think a bit and a little fabricating.

Thats called a BCR. My friend Al has one restored. If he see's this he should post a picture. Haha.

Freightrain Posted December 31, 2012 Share Posted December 31, 2012 Ya, back in the day, BCR converts your B into an R model. The only issue I see with someone putting a B onto an R chassis is the fact the front axle is too wide and the tires stick out. Livable, seen a few like that. Just not my cup of tea.The ones I've seen have jacked the cab up a few inches to clear stuff. Quote Larry 1959 B61 Liv'n Large......................

Maddog13407 Posted December 31, 2012 Share Posted December 31, 2012 RCB right? opposite. haha .might get away with it if you put it on an Early style R model as i think it would be easy to adapt and most had the narrow front axle like a B model. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/29109-how-hard-is-it-to-put-a-b-model-cab-on-a-r-model-chassis/#findComment-154380 Share on other sites More sharing options...

57 bcr Posted January 1, 2013 Share Posted January 1, 2013 Ha,Ha! When I went to our local Mack dealer for parts (for the BCR),the guy at the counter new nothing of the BCR kit and told me they should have made a RCB kit to convert R's into B's! Seriously folks,there was a honey wagon at Macungie a few years back that was a B mounted on an R chassis, I believe.It was on eBay a while ago, and it had ended up in Californy,I think?. Kevin All did one HELL of a job on that B-75 he sold to Kevin Stark.That one is built on a newer chassis,I don't know what model it was on though. 1 Quote IF YOU BOUGHT IT, A TRUCK BROUGHT IT..AND WHEN YOU'RE DONE WITH IT, A TRUCK WILL HAUL IT AWAY!!!

Maddog13407 Posted January 1, 2013 Share Posted January 1, 2013 yup, he said it was a pain in the ass to put in tho cause the holes for the springs are about a half a hole off. it can be done. i remember the honey wagon at Macungie a few years back to. not sure if its the same one or not. the one i remmeber had a Pete battery box set up on it.

Bigdogtrucker Posted January 1, 2013 Share Posted January 1, 2013 What about putting the R driveline in the B? Quote Link to comment https://www.bigmacktrucks.com/topic/29109-how-hard-is-it-to-put-a-b-model-cab-on-a-r-model-chassis/#findComment-154573 Share on other sites More sharing options...
BOB DINGSDALE Posted January 1, 2013 Share Posted January 1, 2013 nothing wrong with that convertion Quote Link to comment https://www.bigmacktrucks.com/topic/29109-how-hard-is-it-to-put-a-b-model-cab-on-a-r-model-chassis/#findComment-154602 Share on other sites More sharing options...
57 bcr Posted January 1, 2013 Share Posted January 1, 2013 What about putting the R driveline in the B?As long as you stick with the 672 cu. in. (675,676,type engines) wouldn't think there would be much in your way. Ron( b61mack) has a beautiful example of a B with an R model powertrrain in it! 300+,13 speed,Mack rears on Neway air,and Matt Pfahl's 350,12 speed,Mack rears on Neway.....SLICK!

j hancock Posted January 1, 2013 Share Posted January 1, 2013 My B75 is running a 285 hp tip turbine setup and it is a relatively straight forward change.Jim 1 Quote JimIt doesn't cost anything to pay attention.

Maddog13407 Posted January 1, 2013 Share Posted January 1, 2013 ok the Tip turbine is the intercooler on the driver side right? the big Plenum that says Mack in block letters with a filter? thought those were only on the 300+ engines? maybe im confused Quote Link to comment https://www.bigmacktrucks.com/topic/29109-how-hard-is-it-to-put-a-b-model-cab-on-a-r-model-chassis/#findComment-154658 Share on other sites More sharing options...

Maddog13407 Posted January 2, 2013 Share Posted January 2, 2013 k, jw, thanks for clearing that up. just always referred to the air to air plenum as a 300+. didnt know they made the 285 with one to, thought the 285's just had the air to air in front of the radiator.

57 bcr Posted January 2, 2013 Share Posted January 2, 2013 The 285,315 (300+),and the 1st 2-valve 350's had tip turbine equipped intercoolers on them.

Maddog13407 Posted January 2, 2013 Share Posted January 2, 2013 exactly. titles really dont mean much on antique vehicles. least not in Ny. you are better off without a title and just havin a bill of sale is better or one you write up yourself so you dont have to pay all the taxes on it. least thats what i do haha Quote Link to comment https://www.bigmacktrucks.com/topic/29109-how-hard-is-it-to-put-a-b-model-cab-on-a-r-model-chassis/#findComment-154798 Share on other sites More sharing options...
