'96 spec ITR master cylinder size and part number? ... non abs.

Does any one know the size of the JDM 96 spec Integra Type R (non ABS) master cylinder?

Would anyone have a part number for the non ABS 96 spec ITR m/c?

I've heard it's a different part to the 1 inch m/c fitted to the 98+ JDM ITR (part number 4610-SO3-Z02).

Thanks in advance :-)

I believe the 96 spec booster and master cylinder is the same as the audm dc2 vtir.
If anyone can confirm that u can get a part number from Honda.
