Thank's Jake
I will put both sender and fan switch down there on the plate ,I am a little concerned about warpage when I weld on the inner tread bosses .
Both switches are very short an will not stand more than 1/2 inch off the plate.and will nearly be flat on the inside 1/4 tread bosses.
I still have not found a remote oil filter mount I like. I am torn between a airwolf aviaction unit. and amsoil twin unit with a backup bypass filter. i wold have rather had a single with a built in bypass valve
