Big truck parts comparison - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have a relative fixing some issues on a non-A/C c40 or c50 truck. Have some questions:
1) is the heater core the same on a non-A/C c10-c50 truck? Can we simply order a replacement core for 10-30 series truck?
2a) Are the steering columns completely different or do any parts cross over?
2b) The left turn signal won't "latch" when pressing the lever down. However, by holding the lever down, we can get it to signal. Does anyone know the fix for this issue? We haven't torn into anything yet to investigate.

Thanks!

Turn signal problem is cracked cancelling cam. That should be same part as 10-30s.
Columns differ, but not at the steering wheel hub end. The steering wheels are the same as 67/68s only a tad bigger (but smaller than 69-72) diameter.

I am 99.9% sure the heater parts are the same. The .01% is because I don't know for an absolute fact.
