For the first generation (1993-1997) the Chrysler New Yorker, LHS, and Concord; Eagle Vision; Dodge Intrepid; and Plymouth Prowler* were all on the same “LH” platform. For the second generation (1998-2004) you had the Chrysler Concord and 300M, Dodge Intrepid, and e the Plymouth Prowler* which are also on the “LH” platform. I’m not sure what that LH stands for, but it’s a reference to those cars.
*The Prowler is of course on a different chassis, but it has the same power-train, it just had the tranny placed over the rear wheels rather then the front ones.
If you’re going with different wheels you’ve got more options then just the first generation Intrepids. Any second generation wheels, including the 18in 300M Special wheels will fit the 1g. Also 300C and Charger wheels will fit as far as I knew.
