I think he may be full of a brown smelly substance...
Just did a quick look at Babbitts Online and searched for the part numbers on Bike Bandit to see what models they fit...

Driven plate part #21451-28C31
I won't list the models, apparently it fits 162 models...
Clutch spring part #09440-19007
Same again, except 73 models, some of which aren't even GS'...
Hope that helps...
PS: Forgot to mention there's a '79 750LN listed there for all three items... could make it a very cheap fix for you
