I see the GM radiator part number I need is 3134414. Is there a way to cross reference this to find a replacement? 1958 3442. Thanks

No. But if it's the same as a truck, they are available in the aftermarket. If it's specific to a step van, measure it and buy an aluminum that closely matches the dimensions and the inlet/outlet locations........ and fit it in there. Chances are really good that they used a truck radiator. Need to look up the old radiator part number for a 58 truck to see.

I found them once and now can't seem to. It's the mounting fins on the side, they are vertical right to the edge of the radiator. Similar to the V8 kind.

Where did you find this number...is it stamped on your tank?

Get something close and make it work. That's the business we are in. Adapt one thing to the other. Chop-screw it up-rebuild. (fabrication)

Bothers me that one time I found them where at least the brackets were in the right place. Seems like they might have been called engine side mounts? I'll keep looking, but I might have to get one and have the brackets rewelded up to the edge.

Here's the listing from my Parts Books,

1.219 Radiator Core Tank Assembly

1955-59 D-D (6 cyl) (2nd series) (exc 2 TON)....(stamped 3135857 - 2" core)...p/n 3135857.

The FAM doesn't always have good part numbers...
