Re-pop rumble hinges - questions

I have a '29 Sport Coupe. I'm pretty much rebuilding the rear sheet metal starting from scratch. I will need replacement hinges, brackets, etc for the rumble lid.

Can you guys give me feedback on your experience with remanufactured hinges, triangle brackets, and braces? One thing I'm awfully puzzled about is the difference in cost - MAC's wants about $15 for a pair of hinges, some guys want upward of $60/pair. I'm kind of suspicious about quality and fit.

Thanks for your input!

Mike
