Daytona wheels on 77 rd400

[RDSingh]

Hey guys, i want to use Daytona wheels on my 77 rd400. Front wheel is easy , but dont know what to do with rear one. I checked tech library, didnt find much information. The problem is the hub dust caps, how much should grind the hub dust cap spacers to get perfect fit.

The spacing is different on a Daytona.
IIRC the drive side is the same, the brake side is different.
