Anything can be made to fit anywhere.
Are you sure you want to use an automatic trans behind a 90Hp. engine??
Remember; the converter will 'eat up' 20Hp. and this is why they were only used in passenger cars.
A pickup truck, with any load at all will be "slow on the draw" everyday/everywhere, especially if you have hills to climb.
Your money & efforts could be better spent elsewhere.
Good luck.
