Good News: I checked the gear calculator and a 5spd over/w 3.21 gears gives 81mph @ 2400 & 64mph@1900rpm. That gives inter-state speeds, so that's plenty for me.

I think I want the narrow frame for this as it would give more options of bed type we use. Bed would go on frame last.
We may be stretching the '78? flatbed frame instead of the '91.

I suppose you saw all the scenic wonders of western Ks. by now?
Thanks,
Cayoterun
