3 speed swap

[khp71]

will a 3speed out of a 70 bolt right up to a 71 with a 4 speed? drive shaft?

It will bolt to the bellhousing, but you will need to replace the driveshaft.

Not sure of the answer, but I just posted a 72 for parts that has a three speed, shifter, and the correct driveshaft. I am just a little over an hour east of you, or could get to the Schoolhouse tavern with no problem (my Dad owns it)

You can go either way. My personal preference is for the one piece shaft because they are usually less trouble than a two piece. That's what I did on my truck when I replaced a 4 speed with a 5 speed.

However, replacing just the front section will be less work and probably less money if you can bolt in a stock shaft.

At my friendly local salvage yard, armed with a tape measure. About 90% of the time I can find one that is close enough, needing no more work than swapping the yoke. For the other 10% I buy one that is too long and have it shortened at a driveshaft shop.
