M3 engine is too tall and slanted. Seight chassis has a larger tranny tunnel than you need. I believe the T5 will go in the space for the Type 9. You need a widebody Sei or widebody if you want live axle. All IRS cars were labelled SEi, which doesnt help whether narrow or wide, was put in the bulkhead moulding. Any car that fits a Zetec/ CVH / pinto will do.
