I see that a lot is being written about the wheels and myself. Not offended here, but let me try to clarify some things.
First of all, I try to answer everyone as soon as possible. Luckily, I'm not glued to the keyboard (that would handicap my life considerable) and I'm not a professional webshop, but still I'll make an effort to reply within 24h's. Please forgive me if sometimes my girlfriend and work demands some time from me as well which prevents me from answering directly. Also, please note that I'm located in Amsterdam, the Netherlands, so there's a time difference involved.
I find it interesting to read additional info about the wheels in the open debat on the forum. I appreciate this a lot and like to thank others to share their knowledge!
In general the best is to reach out by PM so that I can respond. I prefer to set up a personal communication if someone has serious interest and want to ask me questions about their condition, shipping options, price or whatever. I might be relatively young (I'm 37), but I don't have anything going with short text messages "max 140 characters"-style. You leave out every nuance this way.. I rather take my time to inform people well beforehand so that they can make an educated discussion on whether or not to buy. I encourage inspections beforehand or any other option to get a good, clear insight and I can help and assist in shipping(options). This takes a bit of custom work sometimes given the locations I'm receiving, but that's also the reason why I believe a personal contact is more helpful. If that's taking me some more time and effort to sell, fine by me, but I stand for the correctness of my sales and service instead of quick, anonymous sales.
Someone suggested that I didn't know how to price these wheels. No worries, I have no problem with that. I do prefer to advertise as POR as Robvolz correctly stated. I prefer direct, personal contact and sales and (shipping)service made-to-fit. As I respect other point of views on this as well, I prefer to stick to my own principles for reasons just mentioned above.
/Ironblock; I've actually did sent you some PM's. Maybe their overlooked, or there's some technical error why you didn't received them. I can't tell what went wrong then, since I did manage to reach out to others the same way. Could you otherwise try once by PM so that I can reply on that? Maybe this time it does work.
About the question if it would fit under the low arch '66 GT. I'm not super familiar with this model and I'm 100% sure since I've never done the math or tested it, but I presume Kengta is correct. I also doubt it...
