good set of quick and fun rules, only thing that i think is weird is the 1 1/4" redi rod. why not just 1" haha, anyone could throw a car together and have fun pretty easy tho. The bumper welding is kinda hard to understand tho. 6" per side, but then 2 rows on the shocks? is this part of the 6" or separate?

Not really sure who put in the 1 1/4" redirod rule... was before me lol

Been trying to think of how to word it clearer but the two rows is max two rows of weld on the shock ram itself when welding it to keep it in place after collapsing the shock.

The max 6" of weld is what is allowed to hold each bracket to the frame. The frame connects to the bumper on the drivers side and passenger side and each one has a bracket which can have up to 6" of total welding to hold the bracket to the frame.. whew!  :o
