No related RV-4 or other drawings that I've seen. Anyone care to share their details of Back Seat Crotch Strap attachment fabrication? Any "gotcha's" that need to be avoided? Your suggestions and experience is appreciated.
Yours looks much like the instructions for the F1 but there's no details on the part/bracket itself. I will most definitely utilize the available strength of the long's. Was that a 3/16 angle you used?
That could be made to work with an extended bracket (see above). It's interesting that yours is intended for a swivel versus a slot for the belt (above). This is one of those cases where it would help to have/or know the hardware you'd be utilizing in the future.
