Title: Pre-88 Front Cradle Bolts Post by: dguy on April 20, 2010, 12:50:40 pm The original spec for the front cradle bolts is M12 x 1.75 x 105mm, class 10.9.
The closest Ottawa Fastener supply can come to that length is 100mm; the hardest bolt they have which is 105mm or longer is class 8.8. :-\ I think a 100mm bolt will still do it. I seem to remember there being significantly more than 5mm of thread protruding past the end of the nut when I cut those turkeys out in the first place. Will confirm by measurement later tonight... In the mean time, any speculation as to what one might end up facing with a 8.8 bolt substituted in place of the OEM 10.9? ???

I think the only problem you are going to have is with the length. You'll have to order a 110mm length because they are really hard to get a 5 mm intervals less than 40 mm long.
I recently ordered some bolts at class 10.9 hard and they definitely have the M12 x 1.75. I saw it in their book. Also, be aware that a class 8.8 bolt will rust significantly faster. Aaron .

I wasn't so much placing an order as I was asking them to put a few pieces aside for Sacha to pick up on her way through.
As far as 10mm increments goes, going 5mm over on length isn't a big deal so long as the bolts are installed with their heads toward the outside of the chassis. |
