Taper roller head bearings - what part numbers?

[AMCQ46]

I am off down the local bearing supplier to get wheel bearings for my trials bike later today, and would like to get some Tapers for the steering head on the VTR while I am there.

anybody take a note of the bearing serial numbers?

I did a quick search and only found a mention of SSH903R as the standard ball brg part, but will have to research to see if I can work out the equivelent taper

OK, It looks like I already had the answer to my own question!

SSH903R is the taper roller kit number and the bearings are:
Upper 26x47x15
lower 30x55x17
I will still have to work out the seal number
