Spacers for behind a fixed sprocket.

Hi to you all out there. Can anyone point me in the direction of spacers for behind my fixed sprockets .
I am guessing that they are going to have an internal diameter of 33.7mm,the hub is a Miche Primato.
The45Rooster(from L'pool) AKA The Cycling Rooster is back on Fixed Wheel after a 46 year abstention. The bike is kitted out with a "Fail Safe" rear brake as well as the obligatory front brake.
I have built up a 49cm Fuji Track Frame with Mavic CXP33 rims on Miche Primato hubs and a 52T Stronglight Chainring on 140mm crank arms.
Hopefully my next communication does not come via a lap-top from a hospital bed.

I have one dude, hold on and ill take a picture

Hi chickin. If you mean Roscoe Street,Liverpool. It is actually 20miles from where I live.
I am going into the City in a week or so,I will check it out.
My reference to L'pool in my forum ID is because I was born there in September of 1945. Yes I am an old sod & probably the direct result of my father coming home from The Middle East for Christmas leave 1944 and New Year celebrations for 1945.
