Grundig CF-5500 pinch roller size

[8rkin]

Dear Forum Participants,

I recently got hold of this beautiful deck Grundig CF-5500 with non-original pinch roller.

I would appreciate if someone could share its correct size here:

1. Diametre 
2. Bushing width 
3. Rubber width
4. Inside bore

 Cheers,

Oleg 

P.S. If someone has the exact size of the drive belt, that would help too. Currently I am using 85 mm of 1/2 length, 5 mm width.
