my white lude has an aftermarket starter motor on it. as such it does not have that distinctive H22A sound on start up. this is just not good enough in my eyes

the red one has a good OE one fitted and i fancy swapping them over.
am i going to find it difficult? or could i have done it in the time it took to type this?
im off out for a look at the whole job of getting the red one ready for sale but if anyone has any advice i would be very grateful.
