clutch problems in my 76 k10????

[wyo76k10]

alright my clutch for some reason all the sudden slips so bad in 2nd and 3rd when i get on the gas the engine just revs up and the truck wont move any faster? i recently went mud bogging would that do it for some reason? and if i do get a new clutch whats the best way to remove the sm465/np205 combo?
thanks

Take off drive shafts. Remove linkages for transfer case. Remove transmission shifter. Unbolt clutch linkage. Unbolt bell housing from engine and tranny to allow both to wiggle seperately. Get something to help support tranny weight. Unbolt tranny / transfer case from support frame. Slide them back together and drop them on your chest. Lay there until someone comes to check on you.
