Did some digging, 10.9 bolts are rated @ 130,000 psi yield strength. Looks like the ARP Pro-Series flexplate (244-2901) bolts are rated @ 200,000 psi yield strength.. 12-point heads, should look good even though nobody will see them.  Guess I'll give them a try for the rears anyway.
I figured out my "stupid-me" error in why I thought the fronts were M11x1.5 - you have to remove the factory caliper bracket! LOL The front bracket holes are M11x1.5, but are bolted on to the front spindles with M12x1.5 bolts... Mine were so rusted I thought they were one piece and didn't separate them! Whoops. That said, the factory M12x1.5 bolts that held the factory brackets to the knuckles seem just about right for the job, so I'm either going to re-use them or get Fastenal P/N 11114837 if they're in stock when I stop in on the way down to work on the car.. --> Haha! Ordered the bolts from Fastenal, picked them up and went to use them a couple days later - they put the wrong P/N bolts (M12x1.75x40) in the bag, with the right P/N! Awesome.. I re-used the factory bolts, and they seem fine..[This message has been edited by Riceburner98 (edited 07-13-2012).]

Question for you brake gurus. I have an '87 GT which is shortly getting an '88 cradle rear swap. I have a complete 11-1/4" LeBaron upgrade kit but am wondering if anyone has done this swap on '88's as everything I am seeing is for '87 and earlier. Does the same rear bracket work?
Edit: I just answered my own question. Let me ask the question in a different way. What is the difference in the rear brackets between the '87 and '88's?

The subaru rotor looks nice, but the limited factor may just be the rotor hat. I will have to look into this....
Also Wilwood makes many different calipers of different bore sizes to replace the GM Metric Caliper.

I know this is an old post but since it`s relevant here`s my question.
To those who are running the LeBaron upgrade with aftermarket wheels since the shoulder on the front is so small are you using hub centric rings.
If so, do you know what mm they happen to be.
I think the wheels I have are 74.1 bore but I don`t know the LeBaron hub size.

I know this thread is a decade old, but THANK YOU. I'm in the middle of a Lebaron / Cadillac brake swap to the rear of my 87GT that has the Held Motorsports tubular A-Arms on it, your post with the awesome pics, helped me make sense of why my install was different than the other peoples swaps.
I used similar rear calipers to you, but I believe they came from a 79 Olds. I had no interference between the pad and knuckle which I assume is due to the held kit changing things around.
