I'm 16 and restoring a fox body convertible lx and I would like to restore it to exactly factory specs it is silver body with black top and interior 5.0 5 speed now I was under the impression that it was a 92 when I bought it which I know means body color side modlings but I bought a chiltons Manuel and when I de coded the dash tag it says it is a 91 does that mean it was built in 91 and part of the 92 model year or is part of the 91 model year any input is appreciated
