R766ST

712 was the designation for the 300+ which hadn't been introduced yet, but it looks like a 6. A 673 maybe??

The Moonfire Mack was an RL-711LST. 250-horse 673 engine with a quad-box.

The cab over had a 300-hp ENDT 864 also with a quad-box.

I

remember all of this from my younger days due to the fact I ate up everything written in Mike Parkhurst's Overdrive back in the late 60's, early 70's and waited hungrily to see the movie.

I believe the specs are included in the December 1971 edition when the trucks were listed as being up for sale.

"Hunting" is common with cold 6-71's.

Thank you very much guys! I appreciate the help! I planned on using the tranny from the DM600 kit but figured I had to lengthen it. Thank you mowerman for the meaurements!

Hi guys. I build model trucks as a hobby. I am currently working on a RL747 for a Canadian carrier that ran them. My question is what is the length of the triplex transmission? I was told I need to lengthen the transmission I was planning on using. Any help would be great! Thanks,
