o.k. guys and gals, i have a 79 f150 4x4 with (of course) a 351m,4spd tranny and a big old leaky rear seal (barley starting to leak) i have changed out a few rear seals on various trucks (4x4's mostly) without pulling the engine out.
that being said i was looking at everybodies favorite manual (haynes, bleh) and it says i need to yank the engine, loosen all main caps etc. etc. .
my question is, can i just pull the pan in the truck, (i have had it off like that before), and remove the rear cap and change it? or do i need to call a friend to help pull the hood off?

yes the bottom end is fine, it's just age eating at the seal. thanx!
