won't make it any quicker, but will certainly be a lot more comfortable,,
had these Sebring seats in the garage since 2013??
made them the next project,, certainly the instructions and diagrams from the 'corvair kid' are absolutely on track,, I spent time verifying every line of the wiring diagram,, he has it right.
the seats I got were the standard velour-fabric, and really dirty,, they scrubbed up ok, let em dry and hit them with a can of black fabric spray bomb,,
