I was lucky enough to be able to put these L-bracket supports (PHP, 16 x 1/2 x 1/2, item number 20802) under the Tx's and choke for support. It was held in place by the screws that would normally be used, so no extra holes to drill. These brackets are available from Home Depot for around $2. The holes are spaced 1/2" OC alternating between large and small openings. If one were to make a 6" x 6" square out of these and set them off the top plate by using washers, one could have 96 mounting holes and only need 4 screws to secure it to the top plate. This is what I mounted the CCS and heater PS on.....Colin
