Hi Gord, I'm pretty sure that the iForged and the new HRE's have, like my new DyMags, the hidden fasteners.
We're going to get together NEXT weekend (June 27) mid/late afternoon for a little car gathering at Hawrelak. David will be there and I'll ask him to bring for you some information on the wheels he carries or can get for you as well as ordering times etc. I can also give you Rob's contact info as he does tend to specialize in GT's in Western Canada.
