JoeH Posted September 6, 2019 Share Posted September 6, 2019 Download the Truck Paper App on your phone. Thousands of Mack's for sale on there. You'll want to pick R686 for the model number to get the 285 horse maxidyne "300" in those years. I know very little about the 300+, don't know if it was an option in that range. Might have been an '80s thing. Quote Link to comment Share on other sites More sharing options...

Whiskymack Posted September 6, 2019 Share Posted September 6, 2019 R612 or 712 for the 300+ but I think a lot were coupled to fuller roadrangers. https://www.truckpaper.com/listings/trucks/for-sale/list/manufacturer/mack/model/r612st Quote Link to comment Share on other sites More sharing options...
