bearings

[ozzy1]

Im after some bearings for the rear wheels.I have the sierra rear set up with disks.The bearing is SKF BT1B328053.This has a 68mm o/d and 41mm i/d.
I am unsure what particular model of sierra this set up is from.I have tried many local bearing specialists and this bearing is listed as manufacturer only eg Ford.
I have found some cheapies on ebay but never heard of the manufacturer;Vetech !!

I have emailed a few of the other ads on ebay for the dims but very slow response.I know Burton power list some but no dims listed
