Re: Mounting a 6 inch tom
If you are not concerned with being true to using the original tom stand then I would suggest getting a modern Ludwig double tom stand that uses L rods and mounting the 6 and the 8 inch toms on it with suitable mounts like the one shown in the pic. (that is a Ludwig floor tom leg mount on a high tom) You will simply have to drill some new holes in the drums.
The other alternative is to search eBay for an original style mount.
I kind of like old drums:)
