400ex yz450f hybrid

[p0opstlnksal0t]

gotta 400ex with blown motor, about to buy a cheap yz450f motor. was wondering if anyone knows where i can get motor mounts for the yz450f to 400ex hybrids? i know there have been many of these conversions done, but my google isnt turning up any shops that sell these mounts. any info with this swap would be greatly appreciated.

thanks
