I needed to replace my gas tank and bought a plastic 29 gallon tank
made for installation. However the old tank was 60 gallons and 37"
wide, 42 inches long and 10 inches deep. The replacement is 26" wide,
43 inches long and 9 inches deep. My question is from front to back
the tank fits in snug, but has 2 openings (are these what they mean
when they say baffles ??) and is not restricted in any other way and
has plenty of room on the sides and top. I keep reading that the tank
will expand 3% when I put gas in and was wondering if by having the
small areas of the front and back snug like it is, will cause me a
problem. Any help or words of wisdom are appreciated.

Baffles are internal partial walls inside the tank. The object of a
baffle is is to reduce sloshing around of fuel inside the tank.

If the two holes you are talking about are on the outside of the tank,
then they are not baffles. One is probably meant to go to the motor, and
the other one is probably meant as a vent. If your motor is a diesel, you
will probably need a third hole for the fuel return line. (If you already
know this, my apologies!)

Unfortunately I don't truly know whether you need more expansion room or
not, but I doubt it. Most plastic won't be hurt by a little flexing,
especially if it is designed to be used as a fuel tank in a boat.

HTH!
