You think that you have it rough building MOPARs? I started a light restoration on my Buick Turbo T Limited (Grand National Buick, but white, and my third one) in December of 2019. I encountered parts suppliers lying about having parts in stock, not meeting projected back ordered shipping dates, mis boxed parts, new parts that didn't fit or actually work, parts that failed within months, warranties not honored, the same crap parts sold under different names, and same lying vendors selling under different names and addresses.
I sold the almost finished car to the first guy that called, and told him why I was selling it, in great detail, and with a log book of all parts ordered dates, recieved dates, whether they fit and worked properly or not too.
He said I was a "nit picky bastard" and was "too sensative", whatever that means.
He drove the car on his trailer and said he would drive the car here and show me what a good mechanic could do in a week. That was about 9 weeks and new replacement: radiator, computer, deep oil pan, 9" rearend housing, timing cover (integral oil pump), fan relay, and whatever else I forgot to mention later. All of those parts were new and from "reputable" sources when installed.
I had over 4 pages in my book of new parts ordered, and almost 2 pages of new parts that had to be replaced again, and some more than once.
Apparently someone sees a need, designs a part, has 500 made in China, they don't fit, or work, or last, and he sells them all anyway to make his $$$$, and disappers.
Before I bought my 72 Challenger from a friend, I made a list of every major part I wanted, checked stock and pricing, found that everything was in stock from several vendors and bought the car.
The only back ordered part was the duck tail rear spoiler and it arrived in 30 days.
There were a heck of a lot more MOPARs built than GNs and a lot more vendors selling parts with a lot longer track record of satisfaction.
Count your blessings.
There is only one GN Buick board and very little action on it.
Again, count your blessings.
