Man your asking me to show my age! ;-)
If I remember correctly you do need the converter from the TH350, might need
a different yoke for the driveshaft connection, I'm not sure about that
one. As well check that the transmissions are the same length or the drive
shaft will need modified.
The transmission mount and cross member may need to be relocated slightly
and you need to hook up the detent cable from the transmission to the
carburetor so that you have a passing gear.
One other thing to check, call an auto parts store and see if the flex-plate
that bolts to the crank are the same, I believe they are the same part
I believe that's about it, but yes the transmission will bolt up to the
motor as long as it's a Chevy TH350.
The output spline is different so you need the driveshaft yoke replaced with
one from a TH350. The PG uses rods and cranks for the kickdown and the
TH350 uses a cable so you remove all the monkey linkage rods and replace it
with the proper cable which is avail at any parts store. They are 2
different lengths so get the longer one, the short one is for a V6 and won't
reach the carb. Dig around and get the cable support from a V8 with a TH350
or you have nothing to hold the engine end in place with. There are chrome
aftermarket units for this and I think they also hold a throttle cable which
your car doesn't have so either cut it off or if it isnt in the way you use
it as is. If your flex plate has 2 sets of converter holes and is in good
shape you can reuse it. If you need a new one make sure it is the same
diameter as your old one and has both sets of holes. I'm pretty sure the 62
has a 12 3/4 diameter plate. As far as the crossmember I seem to recall no
mods are needed but the driveshaft may need to be shortened and rebalanced.
I know on a swap from a PG to a Muncie 4 speed in a '64 Impala we ended up
having to shorten it by about 2 inches. Other than that it is pretty much a
bolt in swap with GM or aftermarket parts as you want.

Ok i have asked around with no luck. But I want to swap out my powerglide to
a th350/6in tail in my 62 impala. I am told its a bolt on swap. Same tranny
case and all. The shifter is going to be a 64 impala floor shifter with the
shift works cable conversion. thanks
