barry is there a 22 inch t/a aar 4 speed radiator?  And if so, what number?

[Alaskan_TA]

Nope. T/As & AARs all got the 26" as part of the Trans Am package (A53)

[Alaskan_TA]

There are some for 318 & 340 cars though if that would help?

Yes it would help. I really dont want to put an 18 inch rad in my car when I convert back to 318, it just seems too smal, and I have the 22 inch shroud already.  I believe I got a 954 radiator in there now

[Alaskan_TA]

954 is for a 1970 B or E body with 4-speed & heater.

Taking a closer look at the 22 inchers I mentioned last night, they are for A bodies. So, you may as well just use what you have.
