about to fit second hand gearbox

Hi guys, ive managed to find a decent secondhand gearbox and tbox (from a mate who put a v8 in his truck so doesnt need it anymore). Ive had a look over it and im happy its ok, little play and input splines not realy worn atall..... My question is whike i have it out in the workshop what basic things would you recommend replacing or doing to it before i fit? Alrwady planning on crossdrilled gear and will change the outer oil seals but anything else?

Cheers guys

Change yer crank oil seal, clutch lever, clutch and thrust bearing while you've got the access.
