Yes, great advice. I dug out my biggest magnifying.glass and I could see
that neither of the 2 sets of caps and bearings that I was attempting to
fit were a match for this block. Then I found a plastic bag under the
van with the correct set. This kind of chaos is normal for me especially
after 12 months of storage.
With the rediscovered bearings, the ones with the lube hole had
differing numbers stamped (like 8899, 8985, etc). so I could identify
their position on the block with the aid of the mag glass. The shells
that are placed in the caps had the same id nr. stamped, so
identification was made by matching up the wear/shading.
Then (after deciding on the most likely crankshaft) the tightening up
procedure was a success.
