is this the right np435?

maybe:

Sources:
1969-1979 Ford F100-F350 pick ups with small blocks and 2 wheel drive. Look for a 28 spline output shaft and square tail housing bolt pattern. The square bolt pattern is the reason you want the 2 wheel drive version. The 4 wheel drive came with a trapezoid or "A" bolt pattern where the bottom two bolts are further apart than the top two. (The exception is a 4 wheel drive with a divorced transfer case, which has the square bolt pattern) It is possible to use a NP435 with a trapezoid tail housing bolt pattern, but your after market adapter choices are more limited and you'll probably need to find a 28 spline output shaft. Chevy and Dodge had their own versions of the NP435, but most adapters won't fit these transmissions.

Got mine from a '79 F250 2wd with a 400 engine. It had the right bolt pattern and spline count. Perfect fit with the common adapter. A 2 inch body lift made for a lot less floor cutting. I just used the stock shifter boot from the F250.
