What parts are needed to replace a 350SL's 4.5 and 3spd AT with a 5.6 and 4spd AT from a 560SEL beyond:
- exhaust manifolds (will ones from a 450SL or 380SL fit the 5.6?)
- shifter gate plate (are 380SL's the same as 560SL's?)

Will these 450SL parts work with the 5.6:
- driveshaft?
- motor mounts?
- transmission mount?
- shift linkage?

I'll be having a custom exhaust made - what else am I forgetting?

Thanks,
