76 TA R12 capacity?
 

I've just installed a Original Air Stage 3 kit switching everything to 134a. Kit was good but says not to use any oil because the compressor is pre lubed and to add refrigerant to 70-80% of what was recommended for R12. I can't find what the recommended R12 capacity was...….anyone know?? Thanks

Just in case someone else searches for this info, I've found that the original R12 amount was 3.75lbs.
