I am putting in the F-482 gussets for the passenger seat on my RV-4 as described in the service bulletin 97-5-1. However, I am worried that they will not be robust enough; I saw a RV-8 and those gussets seemed much bigger than the ones I got from Vans. Has anyone used the gussets for the 8 on a 4? Would that be advisable? Pics attached of the RV-8 with gussets installed, and the ones I got for the 4.
