Hey I even had one of those brand-new FORD CAB-OVERS (after being busted in IOWA (I oughta went around) for being over-length. It had a 13-speed w/a splitter...what an improvement over the old 15 spd double-shift. It was a piece of s**t.
You were just WAY out of my league!
One of dem dar big trucks,, I was I was.. 10-4 ... :-)
My cat would do 122mph. Not 123, or 124. @2450 RPM. Dyno'd every 90 days and tweaked. :-)
I loved 13sp with a half splitter. Easiest transmission to drive. Well back then at least. :-)
And ford W9000/9050 was popular as all heck. It sure had more room then the internationals.
