FYI, we now have an STC to install the Airglas L2500A straight ski on the Sedan. You can have a choice of the Airglas Bungee rigging or either of the F. Atlee Dodge Gold or Silver springs.
We can supply the rigging complete or purchase the STC and front attach tabs and you can fabricate the rigging from the supplied drawings. You will have to decide which rigging you want because the cable lengths are different for each of the types of rigging and require different drawings for installation.
The STC, drawings and instructions for installation is $250.00, forward tabs are included. I would have to get current pricing for the cable stock, springs, etc. to quote the complete set of rigging of your choice.
