My radiator sprung a leak, and need to repair or replace.

It is a 2998965 ('70 C-Body 383 A/C).

Should be a 2949054 I believe.

Is the 054 a larger capacity radiator than the 965 or should I just get the 965 re-done and re-install?

I could use more cooling capacity in really hot weather, but mostly never had a problem with the 965.

Also, will the shroud on the 965 fit the 054?

Any help or recommendations will be greatly appreciated!

Thanks!

Mike
