WTB 2 1/8 outlet (inside diameter) 318 or 360 Magnum exhaust manifolds

Casting numbers for the ones I want are 53006619 and 53006618. I believe that they were produced for 1992-1993 only. There may be other magnum manifolds that have 2 1/8 outlet and if you will give me their casting numbers I will look then up and see if they will work. The 53010187 and 53010186 are identical in outside appearance but have a 1 7/8 inside diameter on the outlet. I am ONLY interested in the 2 1/8 outlet ones. Thank you!!
