The bolt in frame connectors are pretty much useless. They need to go through the torsion bars cross member and tie into the front frame rails to really be effective.
As mentioned above. I welded in all of the factory holes not being used and painted the snout bars from my roll cage. I just scuffed my engine bay. We sealed, epoxy primed, painted and cleared by re-mixing the same B5 blue from when the car was initially painted.
Welcome and very cool ride. Yes, many vehicles got a quick change over from 70, 71 then to 72 and so on during their racing era. I vaguely even remember that article and those pictures. I know Dave Lyall and work with Dave Lyall Jr. For 30 years.
Anything can happen and be changed in over 50+ years. Who knows what has been added from new or not in some cases. Even dealerships added or swapped parts from other cars on the lot if it helped make a sale.
However, that is a ton of money and for that kind of money the car should be perfect in...
I know what you are saying. Even though I have two trailers. Mostly for hauling projects and for storage. I do however drive the crap out of my running/driving classic cars.
Congratulations. Quite the milestone. My red 70 Charger R/T S.E. has 254,000+ miles on it. Over 205,000 by me over the last 37+ years and still unrestored.
