Me, well, I had a Tiger one left over from when i had a Tiger and i had since modified it.
I have a small denso type alternator in there, although i'd like a more powerful variant.
I've seen the raceline version but it was, i believed, massively overpriced compared to other brackets. If it is machined rather than welded/fabricated then it would certainly be better, but as I have access to millers, i'd rather save the money and make it mayself, especially as i have some special requirements due to proximity of chassis members and other bits.
Hence why i would like a model rather than going out to measure the entire area and construct the model myself.
