898 to Alpha 1 mating...

[KRH11]

Hi All. A new member here with a question. Last fall I acquired a very clean 1978 Century TRV 190. I purchased the hull and outdrive as the previous owner had installed a 5.7 and them removed it for another project. I have a 1978 898 ready to go in but need to know which flywheel housing will mate to the 1985 vintage Alpha 1 drive. Any help would be greatly appreciated.
