2.5 to 4.3 swap

Ok So i have a 87 s-10 and a 91 s-10. the body and tranny are shot on the 91 but the body and tranny in my 87 are good. the 91 has a good 4.3 in it and the 87 has a blown 2.5 in it. me and a couple buddies are going to do a body swap on them but i want to put a manual transmission behind the 4.3 because the 700r4 thats is behind it now is shot i have a bell housing, clutch, flywheel and pressure plate for a 4.3 will the 2.5 tranny bolt to the 4.3 bell housing and work? thanks in advance for an help.
