Hi Harrydale,
Not I, but along the sames lines as above. What motor do you have? If it is V8 then even easier on the engine. I don't know if those have an 'inclosed' steering shaft/box, but i'd think the job is a little easier on your truck overall...As a matter of fact, if some trucks from the 60's use the same power plant, then you can probably use factory brackets and even pump possibly from a later model. PS box will have to be made to fit..same basic idea as above.
The only concern I have for taskforce (that differs from the 38) is the size of the truck. I would bet your truck is a little heavier, SO....that means I'd consider using a PS box out of a larger truck as a doner. That is what my gut tells me, I could be wrong about the weight difference.
