Is a 301 a medium/heavy duty version of the light duty 302? ;)
Funny but I'd much rather have my pickup and it has none of that crap on it! Oh heck it does have a "speed control" that I added in about '76 tho. :/ It's a Dana sold by Sears, the original old "black box" seems like it was $59(?).
I added chrome side window shades other than those nothing's been added to the outside, still has its original paint and NO rust.
Alvin in AZ ('75 F150) ps- if i ever add running boards to it-> shoot my dumb ass ok? :/ pps- oh heck mine has "heat" too damn, sounding more like his sissy-ass truck all the time ;)
