				No idea what these are worth. Pads are almost new. Comes with calipers, backing plates, pads, rotors. I have the long e-brake cables SOMEWhere burried in the storage unit. If I find em we can work something out, but for now the box is for sale.

				They came off an '87       
 
 
I have no idea really if they'd fit the larger 10 bolt. _________________ A redline a day keeps the carbon away! |

				| Knowing gm they probably carried over as many parts as possible. Just wondering if the bracket is similar really. I'm finding that people now think 2nd gen rear ends with discs and/or posi are gold plated. It's not a priority but something I'd like to add. When I get home I'll see if i can measure my spare 3d gen rear and compare to the 2nd. |

				| Do you know what the bolt pattern measurements are on the backing plates? I measured my 8.5 10 bolt, then went to measure the 7.5... umm.. ya.. the drum brake rears dont have the 4 hole pattern on the 7.5s. |

				I'll go measure afterwork sometime this week. 
 
 
I know there are atleast two different 7.5" thirdgen housing bolt patterns. _________________ A redline a day keeps the carbon away! |

				| Thanks. From the info i'm finding 4th gen LS rear brakes and s10/trailblazer rear brakes are direct bolt on's with no problems. So I think the 3d gen stuff should work too. |

				2 7/16" Vertical top to bottoms
 
2 11/16" bottom holes horizontally measured
 
3 1/8" top holes horizontally measured. 
 
 
Makes a trapezoid of sorts.

				Ok. I think its the same. My measurements were off a 1/16th.. but i'm measuring with the backing plate on and with a rusty caliper thats hard to read. 
 
 
So.. any idea what you want at all? I'd like to have them, but its rent time again and this project wasnt high priority. More like since they're for sale maybe I should pick them up. PM me what you think. |

				Doesn't exactly seem to be a hot ticket item. I can wait for when you've got cash.
