The reason i didnt go with the notch is that in order for it to really matter it seemed like i was weakening the frame too much... in retrospect i would have liked to have notched it to the seam... but then on the other hand, now that im adding a watts link behind the axle it was propably a good thing i didnt compromise the lateral rigidity by narrowing the frame ...
one thing that i would have done differently was to ass a cross brace behind the rear seat before it went to uppolstery (the GNX'es have it from the factory)
and thanks for the kind words everyone by the way... feels nice that somone compliments ones work and choices even here on Lateral-1Gen.com
