The replacement heater cores these days aren't the same thickness as the originals. What are people doing to compensate?

I took my original to a radiator shop. They had no problem rebuilding it. More money but better...Joe

Mine is not a concourse car, I purchased an aluminum one when original types were not to be found, very thick and stout. Fit great with no worries of hurting it. Can't see it when installed!

Just following up on this thread. I purchased 2 brass cores from Classic Industries and sent them to a friend’s shop to install them along with a few other parts. When they opened the boxes, Classic had sent aluminum cores that looked nothing like the one that was in the car. Unfortunately, they had already installed the core before they sent the first pic below, so I asked them to remove it and put in another or fix the original. Anyway, it appeared that the original core was not leaking and the mechanic thought it was a tiny crack in the hose that was causing the leak. So, we put the old core back in and they changed the hoses. After about 25 miles, it’s leaking again, so I bought another core and new correctly marked hoses (they were out of stock during the last repair).

This time I got the core from Camaro central. It is brass and 2 inches thick rather than 3 inches like many of the current repops. I also got new clips and tower clamps. While the car is at the shop we are going to replace the repop spiral shocks and rear axle cover gasket. The car should be ready to go for the next driving season!

Aren't the spring ring clamps (vs. tower clamps) correct for heater hoses through sometime in 1968?

Yes, for 67, but I don't know about 68. Owner before me took them off after they were used when the car was first restored. He didn't trust them and I agree. Went with new towers as the old ones were a little oxidized. If I was going to show the car, I'd put them back on for the show.

Default Spring clamps

I have the spring clamps on my car, never had a leak. Kinda aggravating to put on. I took an old pair of cheap pliers and used a Dremil tool to make indentions in them so as to keep it from moving as you open them.
