Classic industries radiator finally gave out

So everything was working just fine then, the radiator just sprung a leak.

I measured the core thickness on my Champion 26” 3 row, it is in fact about 2.5”. Tanks are 3”. Currently I’ve got ~9/16” from the end of my pulley to the fan shroud for my electric fans, so, a 2.75” core would be a no go for me. Hopefully you’ve got the room!

I measured the thickness, from the core support my current radiator is 3” deep. The new radiator is 3” deep. My current radiator appears to have a 2-1/4” core, but the core is offset towards the fan, the core is about 3/4” inset from the front but is flush with the back. I should have plenty of room but we shall see
