Guys, the louvers set that I'm having made look just like factory and fit 74-78 hatchbacks. They are 1/3 less weight, as the aluminum is changed from #6061 to #5052 on the center strip spines and changed from #6061 to #3003 on the slats (but using the original design and shape). Both of these new materials flex further before breaking, allowing the aluminum louvers to give a little. Hopefully this will solve all the current breakage problems most OEM ones have on the spines.
Jake at Visuslouvers.com has sent the prototype over to be painted and assembled by Dallas Mustang, to whom he has given the manufacturing rights and tooling costs. Having just a few made each will cost us (very rough estimate) 329.95 a set. If we can get a group buy with 50 units or more, price drops to 260.99.
If you like, I'll post pics.
