I'm looking for new gaskets and bolts for my Bbs e50s but don't really know what I'm looking for! Is it worth me getting a company to do them as I intend on having the centres painted and the inner/outer lips re polished. Any help would be appreciated

 

If there mag centres
I was told they need some kind of treatment before paint
And don't have them dipped
Or you centres will be in useable
