4spd trans

I understand not saving it.

Short of saving it, you could try to document it and whatever odd ball parts were used.

I'm curious what the shifter looks like.

As far as the Top Loaders strength,

that depends on what version it is.

Which first gear it has will tell you a lot, but I believe there was also different cases which varied in strength.

Top Loaders were used behind big block Fords, so the right one would be as strong, or stronger than a  T-10.

This is a good resource and knowledge base for Top Loaders

Mark the shafts, spin it in first gear and see what the ratio is,

I'm very curious what gears they chose for that tractor engined sports car 

Good luck 

That's pretty cool, thanks for posting it.

it uses the three speed shifter plate on the console.

looks like the shifter location is pretty close to the T-10's location too,

I was wondering where it would pop through.

I've thought about using a Top Loader in my Javelin, since wider ratios are more available, and they bolt right to most 6.5" bells.

As long as it doesn't have a really deep first gear I would run it behind a 401.

It's only when you get around a 3.00:1 first gear that I would worry about that transmissions strength and ability to handle torque.
