To add to Chuck's referral of contacting a Lycoming distributor, here are some suggestions.
Aviall - P/N 75735 Short Tube - stock at $53.68
75736 Long Tube - stock at $45.94
API - stock at $47.89
stock at $41.37
Then
www.cessnaparts.com [
cessnaparts.com] shows $57.47 on the short tube but call for availability and they're showing stock available at $49.64 on the long tube.
These part numbers came from my Lycoming parts manual for the L2C.
Hope this helps you out.
