So here's the replacement next to the old one.  Next up...epoxy new brackets on!!

I finally got my old core out.  It was pretty leaky.  1 tube broke off as I yanked it out.  Dimensions are approximately:

Top to bottom 7 1/8"
Left to Right 9 1/2" Thickness 2 3/8"

I'm attempting to replace it with a non A/C 350 V8, 73-91 Chevy C10, full size Blazer etc. core with very similar dimensions & tube locations.  I'll follow up after I epoxy the brackets on.  Thx!  Steve

Dimensions?

The ones I've seen from the various Avanti vendors are all over $320.  The Dodge Aries one you mentioned looks very different.  Avanti pics included here.

Greetings All,

My 77 has a tired original engine & it's getting rebuilt.  While it's out, I'm upgrading various issues that need attention.  The heater core has leaked for years & needs replacing.  Does anyone have dimensions for the original unit?  I've read that a 73-96 full size Chevy truck/Blazer etc. core is compatible.  Can anyone confirm this?  Thanks All!!

Steve

Hi All,

Any idea what the standard rear axle ratio is on the 87 Avanti?  Were there any optional ratios? Thx in advance!!

That looks awesome!!  Just like the factory would've (should've) installed them.  Well done👍
