Radiator Caps
I played with my cars a little this weekend getting them ready for weekend duty and ran into trouble with my mustang puking out the overflow after i shut it off. Combination of overfilled(i forgot i topped it off months ago and wasnt supposed to) and a bad radiator cap after taking it out and inspecting the seal. No big deal and i lucked out and ordered the same one for it a nos Motorcraft RS-60, which was lucky to find.
Then i thought about the Thunderbirds radiator cap and cooling system and i havent really checked anything out on it other than level, so i went down to look at it.
Everything is fine but i want to flush it and replace my radiator cap on the thunderbird as a precaution anyway since i have no temp gauge on it just an idiot light, but not sure about something so bear with me if this sounds stupid.
The cap currently on it is a Motorcraft RS-51 #16lbs, i dont know if thats original or not to it, and i cant find the same one. Im trying to stick with period stock parts and there are a couple RS-50 and RS-53 floating around but even though they are both the same #16lbs i dont know if they physically fit.
So first, Is the RS-51 correct for my car in the first place?
Second, since i cant find that will the others mentioned fit?
I dont want to just go get a parts store brand cheapie one if i can still get nos period oem parts if i dont have to.
