Here is all the info you need for a sm465. If you need to convert it to a 4wd set up they should have everything you need or can point you in the right direction. It should need a differnt output shaft i personally have not priced one but to be honest you could probaly get a sm465 with correct 4wd extension housing and shaft way cheaper from the junkyard. Hope this helps
