Fiberglass resin? Yup! But I've been cooped up out in the welding/fabrication shop lately with CO2,argon,propane,oxygen and all kinds of assorted gases. (Natural and otherwise

)
Jim, are you using Carreras? From us? If so, I will send you everything from the upper mounts and spacers down to the lower spacers and bolts, complete.
Tom, are you keeping the hi-backs? If they feel good, I would try to mount both sets the same so I could switch them around for different driving moods.
Guys, I'm the "behind the scenes" type of person. You know when certain people stand up front and take all the glory.

But you and everyone else knows who REALLY does all the work!
