thanks again HISSIN50.
Yeah I got form the other post about the block fittinf being 1/4. I was trying to get all the parts needed before I start pullin my old stuff out. his stang is my DD and if I have to make parts runs I have to kinda know in advance so i can do the install at my folks house or a buddies.

The autometer gauges I like are the phantom series. But I might have to go with the pro comp due to the water temp gauges being able to be bought with 12 ft capillary. (for some reason they dont sell a phantom series with 12 ft tubing).
