Does anyone know who makes a good trans temp gauge?

I'm thinking about getting a trans cooler from a 2nd gen and fitting it to my 3rd gen and bypassing the radiator completely.

I noticed on a 2nd gen it has some really long steel lines, I know some guys have fitting it to the 3rd gen. have you just turned the cooler around (to mount it on the other side) and cut the steel lines shorter to fit rubber hosing?

My car is like a KE verada from memory. What is the biggest cooler you could fit in the front? I might need to relocate my horns.

Any help would be much appreciated.
