That is not enough info to go on to narrow down a price. The 72 442 were an appearance option on the Cutlass and as such there was no package that included various options, you ordered the car Ala carte. If the car is low miles and numbers matching and original as you state I would place a value between $35,000 and $50,000. The state of the market is not strong right now and you are in a bargaining position.
In terms of value year by year the 70's are worth the most, add more if a 4 speed, add a lot more if it is a convert. Next valuable are 71's under the same conditions. 72's fall a little lower but are much easier to document because of the vin.
Show me some photos and I might be able to suggest a closer price.
