Correct Radiator Cap For TTA

[TTA984]

AC Delco RC27 is the correct one for the TTA. I put on the newer style RC27, it has 2 turn ears. But the older style RC27 says "made in england" and has no turn ears.

In pic 1 is the new one on the left and the older style one on the right in the first picture.:beach:

I do prefer the new style with the ears on it hower Mike is 100% correct with regards to what came on our cars from the factory (and lots of other 80's GM cars if you want to pick one up).

Note that there's another version that do not say Made in England on them ... they are the same identical RC-27 cap but could have been used on earlier GM cars but not sure.

So if you are looking for a stock style cap reference the photos Mike posted above.
