Before I offer these Slick mags on Ebay, I thought I'd post the info here.
I removed them from my IO360B1F in favor of Lightspeed.

Condition: New...1hr in the Lycoming factory test cell.

Rt mag Slick Model No. 4370
Ser No. 99021292
Cust Mag 66GP - OSANN
Including Gear: 68C19622 V6498 50/98 (12 teeth)
Including harness

Left mag Slick Model No. 4373
Ser No. 99080156
Cust Mag 66GC25SFNN
Including Gear and impulse coupling (12 teeth)
Including harness

Cost to replace: $3000 without the gears, less $300 with core credit.
New gears would be an additional $700.

Asking $2500.00

If one of you could forward this message to RV or elsewhere, I'd appreciate it.
