This adapter was designed specifically for the early models that specifically use the 10mm flywheel bolts. Please send photos of your bell housing if you have any questions.
If your Fiat has the 12mm flywheel bolts this adapter will not work for your application as we have found there to be other discrepencies in fitment.
NOTE:All couplers are machined to be an interference fit and must be heated on a hot plate to 600 degrees prior to installation on the motor shaft.
NOTE: If you are using this adapter with a Netgain Hyper 9 motor you must install a Hyper 9 spacer ring before installing the motor shaft coupler. If your purchased the motor through EV West one is included with the motor. If you have purchased it elsewhere you can purchase one here HERE
