Welcome to the madhouse Darren and good luck with the Montecarlo conversion. I've you are using a FWD Alfa donor then the gearbox issue is already resolved. The drivshaft issue is also fairly easily sorted, you stick with the Beta shafts and CV joints and use spacing adapters to mate the two together as the Alfa has a larger PCD than the Lancia one and the intermediate shaft is narrower than a Beta one. Having said that, does the Montecarlo have a short shaft on the left and along one on the right with no intermediate shaft? If that's the case you may need to source another outer shaft. Linkage issues are also sorted with either full mechanical or cable options available but you may need to modify these to suit the Montecarlo. Good news is that you can keep the Montecarlo clutch mastercylinder, it's got enough capacity to shift the Alfa slave cylinder.
Cheers
Guy
