Tranny upgrade
Working with an all-original F100 with a 240 6 cyl and 3 on the tree. Let's say I want to keep my 240 6 cylinder and upgrade the transmission to a more modern standard shift with minimum mods. What are the best options?

...never mind. You said Standard Shift.

ZF from an 88-96 F250 with a 300, they had an external slave cylinder that can be removed. You'll need to make a custom pushrod to go from the Z bar to the clutch fork, but it should be fairly straightforward. The M5R2 five speed is stout enough, but has an internal slave requiring a hydraulic clutch setup. I have added a hydraulic clutch on my truck, as the 7.3 does not have a mount for the Z bar, it's fairly easy but is still a mod.

The ones I know of have been mentioned already. With the little 240 though, I'd say go with the light weight T5.

So the Mazda and the T5 will bolt up to the 240 with out adapter, mod required for Hydraulic clutch, floor hole and shorter drive shaft. Top loader behind a 300 six is bolt-in replacement with either a mod for hydraulic clutch or remove external slave and fab up a clutch adaptation. Am I missing anything?

The T5 I believe will put the shifter right in front of the bench seat. There is a GMC version used in the S-15 (Not S-10) that has the shifter location at the front of the tailshaft housing right behind the main case. One would have to swap the tailshaft housing at a minimum onto the Ford version of the T5 as the GMC main case has a different bell pattern at the four ears.
And a T5 is nicely geared for a straight 6's torque curve.

You will want a World Class version from a V8, and not a 4-banger.
Here's a good link:
