I'm replacing a leaky oil sender and was wondering if either of these is close to the correct sender for the dash light? This would be for an early (September 64) 65 Dearborn built Fastback with a 289. I would think the sender on the left (WVE/AIRTEX/WELLS 1S6918) to be closer to correct but the sender on the right (Standard Motor Products PS10) is what NPD sent and says its closest to concours.
