The XB32 cases arrived today. About a week late but pretty much as described. Being real early, they are what they call the thin flange type, this is the strengthening flange that runs around the mating face on the outside of the case. Apparently the later DBD 34 cases are nearer 1/2" here, whereas these are about 3/16". Ain't really worried as I don't intend to go racing.
I reckon it will be best to send 'em up to Phil Pearson before anything else, get 'em vapour blasted and inspected. Make sure we're building on reasonable foundations.
