Autolinea crankcase vs tinware

[calibay]

I've just assembled my autolinea crankcase and put on the breast plate under the front pulley. However, neither the original or new one fits. Is this a common problem or does someone make a new one?

I believe the Auto Linea cases are a slighty different shape.

Indeed it would appear to be that's why I think I either need to buy new tinware to modify the one I have

Yep, case is a slightly different shape, mainly on the left. Tin-Snips are your friend here...
