what ones are folk using for wilwood master cylinders with integral resevoirs?

i've heard of ford ones, but i'm not sure on the height of them. ie, how far down the flot hangs. a bit worried the bottom of the resevoir with push the switch up, making it show its ok even when empty

I was on the understanding internal reservoires will not pass IVA as there is no float switch...

Rally Design do a universal float switch that you may be able to fit.

these work a treat...
