Alright, so I have ordered a Raybestos 1350R drum from Mike&Franks
in Germany, it should arrive by the beginning of May.
I usually get all my parts on rockauto.com. If my plan with machining the center hole
and drilling five additional holes works, I´ll buy 3 more drums.
I hope that the bolt circle with 5 additional holes won´t be a problem and I don´t know
much about the specific effects what the drilling and increasing the center hole might
have on the originally balanced drum - if there are any.
One thing is for sure: I´m not willing to drive with old and cracked rear brake drums, I´m afraid of it.
If my mechanic is not able to convert the Raybestos 1350R drum for my Revcon, I will contact
Dexter Trailer Axels. Maybe in that case you could provide me with some contact possibilities concerning
RV salvage yards with Revcons in the USA.
