Hi Guys,

Might want to consider something other than toggle-bolts. I used west system epoxy to fasten those threaded ss inserts that accept bolts. I used cardboard templates. Once that was cured I simply bolted in the seats. Never a problem and no future removal worrys like a toggle-bolt. An added hint. Coat the bolts with mould release and thread them in then set the ss insert in the epoxy. This keeps them clean. The bolt will twist out easy enough. BTW - I filled up where the p.o.s. lag screw was ovaled ou to strengthen. What was on their minds with the lags? I beielve this is the only way to fix my previous and your current problem with the bolsters

Take care
