Jere, are we talking cover or clutch?
The cover will be the one with the different type of operation. The spring type is original and works fine, some find the diaphragm ones to be a little smoother. Can't say I noticed enough difference in a daily driven to have a preference.
Some have had trouble with the diaphragm type working with the normal push rod on the slave and had to go with a adjustable one. (longer)

That would be diaphragm type, you don't have the choice

A stock 4A takes a "diaphragm" clutch, similar to TR250-TR6. To fit the TR4 style clutch will require other changes, like fitting an earlier flywheel (or having yours machined to accept the early clutch) and using the earlier TOB and carrier.
