Hey I just had a quick question for those who know a lot more about bolt sizes than I do!
I am looking for Toyota Part number 91611-60825 (intake manifold bolt)
and
Toyota Part Number 47721D (rear brake caliper bolt)

Toyota gives the sizes as 8-1.25PX65-15 for the caliper bolt and I can't find the size for the intake manifold bolt.
Can anyone tell me what exactly 8-1.25PX65-15 is? I think the 8-1.25 is the length and head size, but not sure on the PX65-15.
Can anyone tell me the size of the intake manifold bolt?

Thanks!!, I am hoping to be able to buy these at a fastener store.

8 = M8 (8mm bolt)
1.25 is the thread pitch

65mm maybe? which sounds right for the brake caliper.
and i have no idea on the 15... might just be part of the part number and nothing to do with the size.

Despite the price, I would still use toyota bolts for things like the brake calipers. All of the structural bolts are manufactured to different strengths, and the specified torque values reflect this. Using an under-strength bolt may result in the bolt shearing during operation. Also, the factory bolts generally have captive lock washers, which will prevent the bolts from backing out.
