Two questions related to installing A/C in an MGB-GT I am rebuilding.

1. Assuming adequate airflow, can the condenser coil of an automotive a/c system be mounted horizontally instead of vertically?

2. Instead of using one condenser coil of "x" square inches, can two coils of "x/2" inches, connected in series, be used? (For my application, the coils would be 10 inches apart.

Thanks in advance for helping out a guy who is basically clueless about refrigeration engineering.
