12v71DD powered mack RS-771L

Recommended Posts

Going to build a very rare r model that was a real factory option from mack. The RS-771L and RL-771L came with a 12v71 detroit and were only built for a few years. To fit the v-12 they used the standard long r700 hood and extended the cowl panel to clear the motor.I have some parts from moluminum, double take, gary wallace and a few guys on ebay.

Some of the parts i have and progress on fitting a steel dash dm600 interior in the r cab. Not 100% on using the floater wheels and tires. Might get a set of the aluminum wheels from keystone.

Very nice work on a cool truck. The Blue one in your thread is owned Mark Hothmer from the KIngston, NY it's   a 1974 , just so you know it has the Plus-3 cab so it would not have the steel dash.  1972 was the last year of the short R cab and the steel dash. You can do the early cab by using the rear panel and the roof from the DM600 or the DM800.  I have a video of that truck coming into  the Macungie Mach show last year. I'll post it if you would like. Here is a few pic from the show of the drivers side I posted on the BMT site a few years ago. I have some of the lengthened cowl area, I'll find them also if you like.   Paul
