hiya im looking at mx5 running gear, and was wondering can I use the prop off the mx5 and if so do I need to cut it down/ extend it ?? if I do need to chop it does any one know what length it needs to be many thanks. Ron.

Will definitely need chopping. Think how close the back wheels are to your bum on a 7 vs an mx5. Exact length will have to wait until you've got the gearbox and diff. Mine was 550mm between the centers of the universal joints.
