33 16v crossmember on a 33 8v?
Crossmember on my Alfa 33 (originally 1.4, but now with a 1.6 8v from a later Alfa 146) is cracked where it bolts to the body, so I got a crossmember along with suspension arms from an Alfa 33 16v. The two crossmembers are shaped slightly differently, but all the important points (engine, suspension arms and body mounting points) seem to be in the same place. Does anyone know whether these crossmembers are really interchangeable?
And another question - my 33 had no ARB, while the crossmember from the 16v came with an ARB. If the crossmember fits, I assume I may also install the ARB - it should not do any harm, even though it was not originally fitted?
