You will find your '50 International is a little too wide for the S-10 track. It will fit much better on a 1st gen Dakota. I am putting a '56 IH (same cab as a '50) on a '96 Dakota chassis, and it is going to work out very well. You will not have to Z it, as the IH cab will sit plenty low on the later chassis. A few minor suspension mods and it is gonna be in the dirt. The Dakota also has R&P, which is a much better steering setup than the S-10. It performs better and doesn't hang out in front of the wheels creating a clearance issue. I picked up my donor as a running truck from a wreck for $300, and it's a factory 318 V8 model. Sold off body parts and made my $300 back. I am using the complete drivetrain, harness and all. Making a daily for my wife out of it...
