...........Good website and good selection of parts. I take it that anything indicated concours would be an ideal original part substitution
No - would never make that assumption. They, like others, likely don't have the same level of expectation as most of us would and at times (like others) they make choices/exceptions when it comes to manufacturing between cost and exactly like original. They also (depending on what year and who is in charge) have made choices based on other demands and what the general customer wants but in the past have been willing to make allowances to provide special requests. I've worked on and off with that company for over 15 years.
Their products (tie rods and A arms come to mind) have been discussed in a number of threads and I've used them on restored cars with success as others have. If you have a particular part your looking at contact me and we can discuss the details and check on what they are currently doing. They are only 10 mins away
