yeah so, um, my car doesnt have one of these fine items. i suppose i shodul pick one up, cause im tired of having to fill teh radiator every now and than. i was told a 2 qt one is fine. however, is there a specific one i shoudl get, ie: one that comes with a mounting bracket, etc?

I don't know about the 75, but I know that the 76-78 had them. Go to the junkyard. Usually they are broken but I have managed to find them intact with hoses, bracket and all the hardware. If the 75 didn't have them, the 76-78 unit can be easily mounted and would look original.
