107 coil spring. I have been under the SL looking at the coil spring layout. The Sl has a front subframe assembly which requires removal of the subframe to work on it. You have to have an engine hoist to hold the engine when you drop the subframe. The Sir Tool and I'm sure anything we design will probably work but working on this front end will require some thought.
