Thanks for that link. Just received the adapter bracket and it seems very solid and durable. Nice anodized 1/4" thick, $88 shipped.
Plan to start converting my '52 3100 single-res master tomorrow. Will remain drum/drum, under the floor. Ordered the dual master listed for '67 C10 drum/drum from Rockauto, was approx $50 shipped.
Hope it fits oriented as shown in picture with master "inside" the bracket so to speak, rubber boot facing forward as original.
If all goes well I'll post an update asap!
