RacnJasn93 was looking for the main block, I believe. I have the harness I took out and is the original from '72 which was a 307 small block from the factory and non A/C.Sorry, I did not bump to the top until right now. If you are looking for BB engine harness I sold mine. But 1972 is different then 1970 engine harnesses. I have those vertical metal channels, but I paid about the same as Camaro Central is charging. You are not going to find them cheaper then that.I would sell mine for $65.00 plus shipping.
If he's still interested, I'd sell the whole harness for a good deal.
The vertical channels I'd be interested in.
