I put a 14 bolt 3.21 rears in mine, and a gear vendors which gives me overdrive ( $3k). For the caddy this gives me great gas mileage, and for the 3 week holiday every year pulling the trailer I will put in the 3.73 gears.

I have installed RE7 bags and Rancho 9000 shocks on the rear, I'm not completely sold on this setup yet, but I'll pass judgement when I've trailered

yours is a 3/4 t, the rear should be plenty strong, I only changed to the 14 bolt for the bigger brakes and easier to get parts (drums go for $225 up here)
