What would be involved in changing a long wheel base 1966 f100 to a short wheel base. Would I just shorten the frame or is it more complicated?

thanks

Generally you'd also have to shorten the driveshaft(s) or get a new one. Rear brake lines shortened or replaced. Emergency brake cables swapped out for shorter ones. Electrical wires running to taillights would have to be shortened or rolled up some to take up the slack.

Just some thoughts.

Wheelbase is 14" shorter.

129" - 115"

Overall length is 20" shorter, assuming F100 Styleside.

207.6" - 187.6"

Not counting rear bumper in this case.

It's been done, and more than once

The difference in the actual box length is not all between the back of cab & axle centerline, the measurement from the back of the box to the axle centerline is also different.
I would try to get someone with a SWB model to come by (or go see them, and study both trucks carefully. Take some measurements, make some notes, take LOTS of pics, then make a plan

and for further study, here are LWB & SWB frame drawings.....

SWB

 

Thanks for your comments. This would not be a simple job so for me this question has been answered and I will not pursue this idea.
Thanks for you input.

What's complex about it? If you have the right tools and are a GOOD welder it is pretty cut and dried.

 

Dan - Vic had posted this picture of one that was in his area around Spokane. 4x4, of course. Looks like a fun little rig. Stock SWB in this case. You need one of these, I think.

I have a nice short bed 66 frame and style side bed w/ toolbox

 

That is a dream project of mine. '66 F100 4X4 (long or short, I kinda prefer long though) with a turboed 500 CID aluminum FE coupled to a Tremec 6 or 7 speed. Stock height, or even lowered a touch with a nice patina.
