Can anyone identify these semi-pp housings and what they came out of? Currently sandwiched between 84' GSL-SE irons but I don't want to complete this build if they're not compatible. i.e. spark plug location, etc.

Thanks!

so afik its like this
1757-10-100 are the 1974 Big Port, Big Font housings
3775-10-100 are 1975, small port, big font
8712-10-100A/8712-10-150A are 76-77 are like this but it says Automobiles between the 13B, and the Mazda
N304-10-100C, 84-85 GSL-SE have a smooth top, which is how you tell its a converter vs thermal reactor
N307-10-100 are the 83-85 JDM Cosmo housings, i think its like the GSL-SE but smaller port?

and then these 78-82? thermal reactor casting, like 76-77, but it doesn't say automobiles. or if you like 8736-10-100A/8736-10-150A
