Q: Intercooler tube gaskets on 1990 Ford Thunderbird SC

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
I recently bought a 1990 ford t-bird super coupe. Doing some repairs, in the process found the intercooler tubes were sealed with a sealer, not a gasket. Found out that there are gaskets in 3 out of the 4 connections. Ordered the parts from a ford dealer, but they don't seem to line up. The part number is E9SZ-6F088-A. Is this the right part for the year & model? Are there better Gaskets/o rings avaiable?

Possibly the vehicle was customized, people do this a lot, in that they add aftermarket parts to make the car go faster and/or perform better. I would check the parts with the diagrams from Ford to be sure.
