YES, go through RCR/Vicki. She is pretty on top of things and will typically respond quicker. I have been in constant contact with her the last 3 weeks.
I ordered a MK1 GT40 in April 2016. Picked up in Dec 2016. Some parts that I had paid for when ordered were unavailable for pickup when I arrived. Now one of the parts is ready (at the vendor who is luckily in Austin), and I'm just trying to schedule picking it up. Vendor will not release without contact with them.
Sadly, I haven't had luck getting a hold of Vicki by email or phone yet. Fran sent me an email, but I haven't been able to get a hold of him since either.
If anyone talks to them, please let them know Ven from Austin has been trying to get a hold of them for a couple weeks now.
