first purchase from classic industries

I have a restoration shop & work on all makes & models. Have had both good & bad results from Classic Industries. Bought replacement gauges (temp, fuel, amp) for a 69 Road Runner. I was boxed wrong (got 2 temp gauges), but they DID expedite a replacement, which was the right thing to do.
Both the temp & fuel gauge (bought their temp & fuel senders also) were not calibrated properly & I had to shift them using resistors to get proper readings.
At $90 per gauge I was expecting them to be of higher quality. I think they need a better QC department to track & correct these issues BEFORE we have to!
