A/C line size issue. '77 C30 6.0

New parallel flow condenser has a #8 inlet and a #6 outlet. Factory evaporator line where the orifice tube is appears to be #8. How do I transition sizes?

Recommended driers? Stock replacement? My condenser came with a drier and binary switch. I'm planning to add the GM transducer switch/sensor in the compressor discharge line.

you can get a #6 fitting for a #8 line.

Thanks. I actually called them and they walked me line-by-line through the system ordering the correct fittings. One was the type you listed. Got a new accumulator through them as well.
