Leo:
The bearing caps are machined at the factory in place on the block due
to the
tight tolerances needed for the main bearings. They cannot be swapped between
blocks, and they must be installed in the proper orientation. In short, if
your bearing cap is toast, you cannot source a used one to replace it without
extensive machining of the cap and block to get it to fit. This is why they
are generally unavailable as a replacement part.
Your best bet is to have your existing bearing cap welded, and machined
to
repair it. However, if you are doing this, there is a good chance that after
all the machining and line boring you will have more into it than a used block
will cost. Consider replacing the block with a used one from any of the
British wrecking yards as an alternative.
