Well, I could speculate just to post some kind of reply like the others, but that would be absolutely worthless.
but on the other hand, having spent over $10k with UP in the last year or so....
.... I can answer just about any question you might have.
If you're wanting to order parts from their on-line store, that ain't happening. It shut down last October. Their on-line store flopped hard due to IMO, mismanagement. The story (as of today) is they will be offering their "unique" parts to include the CS signature items through a new (yet to be established) dealer network.
They'll have to do some damage control to regain any of my business. There were blatant lies told while waiting over 6 months for paid for parts.
Their previous on-line store manager (Dave) has left UP. They have a new guy (Ryan @x138) still filling back-orders from before last October. He's doing a fairly capable job, but I feel he's fighting an uphill battle with the upper management (pure speculation on my part). I feel that UP really wants to focus on car building.
UP had a real good idea. One-stop shopping for all your high-end Mustang needs. They obtained a licensing agreement with CS to develop and sell "signature pieces". I think they were overwhelmed by the sales from their on-line store. Buyers were "world-wide" and spending a lot of money... not $1k, but 20, 30, 40k. Coordinating all of this must have been a nightmare.
What if you made homemade cookies for the gas station down the street to sell. You figure one or two dozen cookies a week should cover it. All of a sudden you get an order for 50,000 cookies, they're paid for, hungry cookie eaters are waiting, but getting hungrier every day, and you need to ship them all over the world. Can you say "honey, hows the oven working and sit down cuz we have a problem...."
I don't think they were prepared for/envisioned 1000 people ordering parts.
Your shifter handle.... it's a "shelby" piece. You're going to have to wait.
