Rear Main Seal?

[armybyrd]

Time to change the rms on my 83's 305. Ive heard for the 2 pc rms its not necessary to remove the engine or tranny but itd be a lot easier with them out. My plan was to just pull the engine and clean the block and bay up while its out. Would there be any problems with leaving the tranny in? Also is it necessary to remove the radiator and parking brake cables like the Chiltons manual says? When Im ready to hook up the engine hoist will I be able to just remove the carb or will removing the intake manifold be a must?
