Taijutsu

I'm rewiring the AC circut of my 74. The damaged relay #1243383 was discontinued 9 yrs ago. I need a replacement. The catalog shows several that could fit.This relay is mounted to the firewall towards the pass side. It is a 4 blade relay w/3 in a triangle. Can i get some help here? TIA

You might ask this in the factory correct forum to see if they can tell you what works.
