Year: 1970
Make: chevrolet
Model: el camino
Engine Size: 396
Refrigerant Type: a6

I just installed a big block in my 1970 el Camino(had 350) and I am using some 71 brackets but my question is the location of the plug which is in the wrong location. If I remove the clutch is the plug part of the assembly and can I then locate it in the proper position?
The plug is jammed up against the bracket:


Should look like this:





Thanks.

Remove the clutch, then the pulley, then the coil-- all are 3 separate items- then rotate the coil to desired position and re-install- clutch and pulley are press fits- need special tools unless you are creative-- there are tool kits out there...to be bought or borrowed.

The number one A/C diagnostic tool there is- is to know how much refrigerant is in the system- this can only be done by recovering and weighing the refrigerant!!
Just a thought.... 65% of A/C failures in my 3200 car diagnostic database (GM vehicles) are due to loss of refrigerant due to a leak......

Thanks. Do you think Autozone,etc. will have the tools?
