I had a rough time working with auto instruments.. quoted me 2 months and it took 6. the voltage regualtor they sold me was junk. they for some reason couldn't remove the roadrunner emblem on the passenger side wook grain strip (71 roadrunner) so they sent it back to me at my expense and I was able to pop it off if 2 seconds. sent it back and then they had issues removing the a/c vents on the same peice. they then sent it back to me AGAIN at my expense and with no experiance, used a heat gun and had all 3 vents out in less than a half hour. paid to have the roadrunner emblem chromed and detailed and when they sent it back, they just chromed it and after asking why is wasn't painted also, they told me they weren't doing it anymore but still charged full price. in the end, I sent a few things over the instrument specialties to be corrected.. I dont want to whine, but this was my experiance with them and I wasn't too thrilled..
