1989 4runner Heater Core search

I've been on the search for the correct heater core for my 1989 4unner. I bought a few different types but nothing seems to be an exact match. The OEM core had tubes that use c-clips to mount to the core. I have not found a new core that fits these tubes. First, is Spectra 94662. Dimension are 7 -7/8 tall x 5 1/4 wide. This cores states it uses OEM pipes. but is too small

 

APDI/PRO9010206{#8710789111}
Core Depth (in) 1-3/4
Core Height (in) 9
Core Width (in) 6
Front; With Heavy Duty Heating; With Rear Heater

this one is too big. Fits 1984-88 4runner/pickup..

 

APDI/PRO9010006{#8710789112}
Core Depth (in) 1-1/4
Core Height (in) 8-5/8
Core Width (in) 6-1/2
Inlet Connection (in) 5/8
Outlet Connection (in) 5/8

 

Napa has the one that fit for my 88 pickup. Let me see if I can find the part number.

 

This was the part number that was a perfect fit. NHC 6603348. It was the one that was about $40 bucks.

whatever you do, do not mess up those C clips. You will need to connect the old hardlines to the new core.
