v-max final drive

[turbota2]

I have decided to go to a V-max final drive on my '03

Venture.

I have found some but either to much wear or way to expensive. I did come across an '88 final drive in good shape but I don't know if it will fit. Also I am looking to change out the gears and not the whole unit. I haven't done this before and I figure someone here will know. Ya'll have always come through for me.

Thank you.
