The TQ hasn't been made in nearly 40 years but there are still new ones out there. I have 5 NOS early ones. I used 1 of the new ones on my Polara in my avatar on the 440. It works flawlessly, always starts, and NO vapor lock. And -NO I didn't have to rebuild it. I installed directly out of the Carter box, adjusted a little bit and I haven't touched it in 10,000 miles.
