Hello I am at present restoring a CB550F I have the engine rebuilt into the frame, but still require a couple of engine spacers collars, the collars are at the rear of the engine and upper of 10 mm hole diameter and a lower collar with a 12 mm hole for the lower bar. or the dimensions so as I can get a couple machined. I alo require some suitable heat resistant oil pipe, for the oil strainer in the sump pan. It is part number 15155333000 but is not available anymore. Any suitable alternative pipe I would welcome the information.
