dana 44 gear ????

[drok123]

i am trying to buy a gear set for a dana 44 front end for my chevy. it is a front end out of a 70s model chevy. a guy has a set of spicer gears for sale. but i dont wanna buy a set of gears that dont fit. he gave me all the numbers off of them. he said they were standard cut low pinion gears.

these are the numbers he gave me. dana T
