Thanks guys, after much research, we are still torn between going with the .083" wall vs going with the .116" wall Smith Brothers LOL. I mean, the spring pressures aren't outrageous, only around 128 lb on the seat with the Crower 68404 spring installed at 1.550", and around 310-315 lbs over the nose at max lift. Read many builds using the .080" wall just fine with more pressure than this, so I'm sure they would work fine, but on the other hand, we know the thicker the pushrod, the better, but then again if we don't need thicker.... hahaha.... there is about $40 difference between the two.....
