The trans is direct, not OD, so would be less desirable than OD box. If there is a furl pump just like the one on your 228, most likely not military, can also look and see if lower front engine mount or side of block mounts. I would go for the 302. I presume your truck has 8 on 6.5” wheel bolt pattern? Rear ratios probably low and lower, so not very useful, D-70 axles with that bolt pattern can have
Higher ratios, single speed, easily exchanged, measure overall axle and spring perch widths to get correct one. Might have disc brakes which you may or may not want.
Should work well with direct 5 speed.
