GS750E Twin discs Front brake master cylinder trouble getting 1 or Repair kit

[COLINMACA]

Any advice would be appreciated thanks in advance 

I have tried Robinsons Crooks vintage suzuki parts in fact every  site i can find not 1 outlet has a 5/8th bores repair kit 

There is not 1 kit on e-bay ( lots of kits but all for a single disc 

Part numbers is new part no 59600 -45811 and old part no 59600 45810

Bikes ready to go just a quick tidy up wires etc air filter fuel tank and rear section and chain guard a genuine 11k miles mostly original parts wise upgrades electronic ignition new coils will be fitted brembo brake pads hel brake lines and because i built it to ride a 4 into original exhaust still looks great

Surprised to hear the repair kit is proving so hard to get! I'll be needing front & rear kits when I start mine. Don't forget to post your results.

Will do Toni 

The rear is easy to find and the single front disc one 

Just remember to ask for the 5/8th bore or 16mm 

I asked 3 e-bay sellers is it 5/8 16mm they replied YES!! And they wasn't then complain about having a return  ?

How about M&S, Wemoto ect?

And, most Eblag sellers will tell you owt! Trust no-one!
