Tailcone Bushing Problem - Page 10-04

Wanted to post the following information received from Van's. The SB437-4 bushing will not fit in the hole in the F-1211-A bulkhead. My bulkhead has the same problem that a friend's had. Page 10-04, Step 14, Figure 3.

From Joe Blank at Van's.......
"The SB437-4 will need to be drilled out to 7/16"
