Is the Pontiac one of the transaxle cars they built, I think or 63?

[Hemi Moose]

Yes it is...and here's a couple more Super Duty '63 Tempests called 'The Farmer'.

I was just wondering but did the '62 and '63 Super Duty Pontiac's both come with 'Swiss Cheese" frames or not...or was this a one year thing only.

The information states,,,,,,,,,,

1963 = Swiss Cheese
1962 = Modified rectangular-shaped frame rails, to channel-shaped.

NHRA lists the 1962 Lightweight Catalina SD-421 at #3608 lbs., I believe.
