741 x housing

Realizing this is on a 64 dodge d100 three speed manual truck and not an a body mopar, I’d still like to ask the question (since the resources for this model truck is very hard to find and the car setup might be same) trying to figure out if this is an 8-3/4 ? Would like to buy new seals and gasket and reuse this rearend even with the tapered axle shafts… if this is a bad move please chime in with recommendations and experience you might have with this setup..thanks in advance..
