Getting ready to update my 80SC from trombone to carrera oil cooler without fan for now. Got all parts except the pictured "horn relocation kit" which is NLA. Right inner fender support is PN 911-504-080-00 or 911-504-080-00GRV. Is there a difference in the stock part itself or is the "kit" something special? Can I just use a regular Carrera fender support, fab a horn bracket and move it forward? Anyone holding on to a "kit" they care to part with or a stock fender support if that can be used with a fabbed horn bracket and relocated?
