Sorry for the hold up on the s/n it took me a few days to get over to the machine. my machine is 87A2920
i understand exactly what your saying with the shroud.
also i have the top and bottom i guess tanks for the radiator, I'm just missing the core because some one decided it was worth it to cut it out of my machine for scrap..
with that being said depending all on prices and availability i rather throw a compete radiator in there then trying to replace just the core and having leaks.
Well going with that S/n Cat does say obsolete, but we kind of knew that already!
Cat part number is/was 9S4103
A quick Google search on that number shows a few hit one of the first is:

If you scroll down the page you can see the 9S4103 is available with two options first #225037 with brass fins and #225846 with steel fins. No price listed says CALL. Looks like they have warehouse down in PA.
If you are looking for a complete radiator I'm thinking finding a new one might be out of the question, and a used one would, in my mind, be a very iffy thing to purchase do to the age of anything out there. If your tanks have the strips the bolts go through to hold the bolts it is not that big of a job to replace the core, just lots of 3/8 bolts! Just make sure you make notes and take pictures so you get the core in facing the right way! Have seen that mistake made even by a radiator shop!
When, or if, you do get ready to rebuild this radiator there are a few things I would strongly suggest. First would be to rebuild the radiator cap with new seal/gasket. Second replace the pressure regulating valve, that is the smaller round thing with the five bolts to the left of the radiator filler cap. Let me know if you need part numbers for those parts.
