Made almost two passes with a new conversion kit from Chrysler with an orange box. The orange box failed new on the first pass and I returned it to Mancini at the track and took another orange box and I almost got to the end of the second pass with new orange box and it failed. Walked over and paid 10 more dollars I believe and got the chrome box in exchange and it has been in my street-strip car for 30 years no problems. It would be nice to have an easy repair to all these failed orange boxes that every one has. I just gave up and moved on to the Chrome box.
