have searched the forums to no avail...
Im building a 1380 at present and have a couple of early 1100s (1275) blocks these are the pre a plus type.
Both are missing cranks..
I have a cooper s crank and also an A plus large journal crank.
Is there any modifications required to fit an A plus crank into a pre a plus block?
Being from Australia its not as simple and getting hold of a newer block as they are rare... only know of a handful from Japanese imports.
Any advice appreciated.
