Been overthinking an ECM / relay/fan controller mount ... so I just got some 22ga Al sheet and started fabbing something up that would fit in the passenger hole. I do thank Scott (SlowProgress) for his replies, I started thinking I could use the template he made ... but with the inners things were different.
So this is what I came up with, KISS, I will need to transfer dimensions to some thicker Al of course and use some rubber bushings to mount the fender side plate.
Thanks for looking ...
