I run this site mostly single handedly whilst also having employment elsewhere so although all orders will always go out by the next working day (unless we are out of the country in which case a note will appear at the top of every listing), items such as questions and feedback are only dealt with as time permits. I supply mostly parts for Triumph T120 and T140 but also offer other parts where they are easily available. I only sell on ebay so unless you have one of the two models listed above, I won’t be able to help with other parts. Reference gasket sets, if the gasket you want isn’t visible in the listing photograph, ask me to send you a photograph of the gaskets laid out individually. If the gasket still isn’t visible, it won’t be part of the set I offer. Please note that I only know the application of this part as stated in the title and / or description. I do not know what others models this part will fit. I am not a technician or mechanic and am not able to offer advice on the fitting / application of this item. Thanks.
