Triumph Repair: ends and mains shells, tr7, 2 litre, triumph sports car, vandervell

Question
I have stripped the engine, and mean to replace both ends and mains. The shells I have taken out are, I am certain Vandervell, but there is no sizes stamped on them, only part numbers. I have been on the Vandervell site, and they don't list the TR7, every other TRiumph sports car, but not the 7 or the Doli Sprint.
    The part numbers are VP5104 at one end of the shell, and 145396, at the other, and that is on a big end.
     On the mains shell, the part number is VP5103, and 143040.
    What I would like to know, is a cross reference to another bearing manufacturer. I hope you can help me, many thanks in anticipation.

Answer
Tony, sorry but I'm not going to be of any help on this one.I didn't do any work on TR7's and I can't think of anyone who is glad they did.I always took the block,crank and rods to a machine shop and let them handle it,then I would assemble it myself.I guess keep searching the web for TR7 parts and mechanics.again sorry I couldn't help.David
