I had an optimill quick release boss on my last Defender with a mtolita wheel and to be honest I didn't find any difficulty in lining things up it just went straight on. I marked the top centre of the shaft in respect of the original steering wheel position and fitted the column element square to that, Think they make them to fit square to original fitment wheel. I fitted it because Defenders were getting nicked all over the place. Just in case you are interested I also bought the locking boss cover which when fitted spins freely preventing mole grips being used to steer the car enough to get it on a trailer! Also an optimill item Called a security cover.
