Rega p25 changing to a p8 double pulley

Rega p25
I am trying to change the Rega p25 pulley to a Rega double 33rpm pulley which I bought on eBay from a dealer which is for a ‘RP8 50Hz Twin belt motor pulley’.

Has anyone else done this and can give any advice?
I have bought a bearing puller to remove the pulley,

as well as twin silicone belts.

The replacement pulley is not only taller by approx 3mm but a smaller diameter by approx 4mm.

Just to add I am worried about the speed with the difference in diameter , and it is a 230v 50Hz TT
