T18/T98 swap?

These are truck transmission with a granny 1st gear. Are you considering putting one into an A-body?
Sorry no, this isn't an A-body question and I apologize. This would be for a 68 m715 military Jeep that had a 232 swap at some point. I'd like to give it a V8 for working power, LS swaps are of course very popular but I'd rather go with a mopar engine if possible, but vintage mopar Jeep swaps are rare.
