ok cool - so like many have done, you can get a 3.55 takeoff from ebay (https://www.ebay.com/i/163820423955?chn=ps&norover=1&mkevt=1&mkrid=711-117182-37290-0&mkcid=2&itemid=163820423955&targetid=593772385813&device=c&mktype=pla&googleloc=9032443&poi=&campaignid=2086169716&mkgroupid=76147899766&rlsatarget=aud-622524040958:pla-593772385813&abcId=1141016&merchantid=101712330&gclid=CjwKCAjw-vjqBRA6EiwAe8TCk4UuYD-d7fyC7JlzRoTFNNJRhW1uT81ykoTyWvevwltafjhPcXt9jxoC_ rAQAvD_BwE), or other store... who's the recommended vendor nowadays?

I haven't seen anyone recommended but could have missed it. Just be sure you get it w/ the brakes included. Mine even had the park brake cables which I used.

I bought a complete 2016 mustang IRS with 6k miles for $800 shipped. 3:55’s, traction-loc, and brakes. Bought it on eBay from “the parts farm” in Georgia.
