1963 B40 Rectangular Sump Plate Replacement

[stevehayward]

I am looking for a replacement sump plate that has a drain hole in it.  Anyone know where I could get one?

There is one on e-bay, item number 222890263786. It is more expensive than the one in your link but comes with gaskets, filter, etc. including longer studs which you will need due to the extra thickness of the plate compared to the original steel one. There are lots of A group available but only one B group that I could see and they only have one left. Hope this helps.

Thanks for the link I will contact the seller as it looks slightly different to mine (or perhaps it's me).
The cover on the bike I have appears to be more of a rectangular shape, will have a look later to be 100% sure.

My uncle has given me the bike (1963 B40 twin seat road version) I am slowly working through it, replace the loom and did a 12v conversion. Decided to replace all the hoses etc and improve it for easy maintenance.  My 1st Brit bike, this bike has loads of sentimental value as being the first proper bike I ever rode.

Those sumps are square and will not fit you bike. The only B40 they will fit are the 1966 on models.

Thanks - looks like I'll be fitting original back and making sure I have spare gaskets.
