Were the few 916's equipped with the GT stiffening kit?

Other than the obvious rigid roof, were there any chassis stiffening improvement to handle the larger powertrain/gearbox?

@Montreal if you have a bit of time during your 4 to 6 conversion> you should definitely schedule your chassis reinforcement kit installation. Having to go back and do it once your 6 is converted and running is a lot more work.
Starting in 1976, club racing / time trials in the 914>with a T4 2L boosted at 7psi started a few hairline cracks in the inner ¼ panel/ fender well sheet metal areas. I didn't even know about the gt stiffening kit, and just left as is. In 1978, I converted to a 2.7L 6 and raced at same tracks RIR and Willow, still left the weak rear inner fender areas as is.
In 1985, when I installed 3L biturbo, and GT steel flares, 916 trans, 8 point cage; I located the stiffening kit + welded that as well. When we sanded away all of the undercoat and paint the sheet metal damage was seriously worse than just a few cracks.
