very easy.
you need the correct momo hub, and the wheel itself, along with the momo or porsche horn button.
step one, pull the horn pad off the stock wheel by twisting it 45 degrees to the left IIRC
step2, use your 27MM socket and LOOSEN the nut that holds the steering wheel on.
step 3 - to the best of your knowledge, get your 914 wheels pointed straight....
step 4. remove fat nut holding steering wheel on, AGAIN - making sure it is pointed straight.
step 5. use SOME muscle and PULL steering wheel off the splined shaft
step 6 - have a beer.
step 7 - see step 6
step 8 - unscrew the 3 little philips head screws on the back of the stock wheel holding the copper HORN CONTACT RING to the stock wheel.
step 9 - transfer said hornring to new momo hub. route wire through the hole in the momo hub.
step 10 - screw new wheel onto new hub, with 6 inclyuded hex head cap screws.
11 - push hub/wheel assembly onto splined shaft...doing your best to make sure you have it in the correct orientation.
12 - LOOSELY put the nut back on....
drive car to see if the wheel is straight....if not pull off and rotate one or 2 splines in the desired direction....then TIGHTEN the nut. THEN....put horn button on with spade terminal....
DONE
then send a 12 pack of sierra nevada to me
