FLM Hybrid Bulks

[Hustler]

Thanx a bunch for the advice guys. UE it is then. I went to the local hobby shop and he says I cant just buy the bigger cup for the center drive shaft? What are my options? Do I have to get the whole 1/8th scale, buggy center drive shaft set or can the UE center shaft for emaxx work?

Also, I am only changing the front diff and bulks at this time coz I had already put integy bulks on stock diff in the back (for now that is). Later, do I have to have the exact same setup as far as diff and bulks go or I can have something different in the back? I know I'll prolly need the same diff set, but what are my options for bulks and diff covers?

Can you guys suggest a few diff setups?
