Will an 8 3/4 rear end fit in a 73 dart sport?

Ended up putting it all back together. Just purchased some local headers that will fit, and exhaust to the rear axel. Also have a new gas tank. I think i will end up dropping the whole rear-end with the leaf springs and will have it all rebuilt. Previous owner changed the leaf springs mounting locations I believe, and they also appear to be very poorly welded. I think i will keep the ford 9 inch just because it does fit currently and the driveshaft mates to it as it should. Will end up replacing wheels, tires, u-joints, shocks and some other stuff while its out. However, I will have to figure out why the leaf springs look modified..
