Re: Running a bit hot,,,Question!

[Jim Altemose <jaltemoose@xxxxxxxxx>]

Bill,

When did they start adding the overflow tank?  Is there a good source
for these?  I have a 63 Polara 500 and it probably be good for me to
add since I drive it a lot.  I'd like to look as close to period
correct as possible, but it's not a show car and good performance is
more important to me.
