alexedit.... I installed a .61 GMS on mine. I used the Dave Brown round mount BRO 60-70. I redrilled the holes in the mount to match the blind nuts in the firewall. I had to make a small V notch in the edge of the mount so the throttle linkage would clear. I also beefed up the inside of the firewall with some tristock and epoxy. Swapped out the stock wheels with 3" foam all around, put a longer nose gear in out of a Tiger 60, and I am running an 11x7 MAS Scimitar. I use the Bruline filters on all my planes. Keeps the grass clippings and junk out of the carb.
