According to the latest early S registry list I have the following chassis and engines are listed together (note: these combinations might not all be matiching #'s):

9113300854----6631315

9113300861----6631329

9113300902----6631421


6631126----9113300720

6631164----9113300752

6631169----9113300755

6631174----9113300756

6631184----9113300759

6631161----9113300774


These #'s cast a little doubt on 870 matching with 1154 but strange things happened sometimes when these cars were built so you should get a CoA to know for sure.
