I've yanked one out with the NP205 still attached using a floor jack with the tranny adapter that slides in place of the usual saddle--I bolted the adapter plate on the jack to the crossemember and removed it all as one unit..
Once at a friends house we did a clutch in his 4x4,and he had no jack or engine hoist--e removed the floor hump and put a doubled up 2x6 across the cab, by rolling the windows down and lying them in top of the doors,and we used a small chain falls to support the tranny enough to slide it back away from the bellhousing...I've used a engine hoist before on one truck too,we remoed the passenger side door to make it easier to get it in there...one guy I know used a chain falls on a tree branch,with the chain coming in thru his sun roof to lower his tranny and T-case out !...lots of ways you can do it,just be careful,the SM465 and a NP205 are both heavy ingots and will crush fingers and arms FLAT if you get them in the wrong spo,or they drop suddenly...!...
