Pre-88 Front Cradle Bolts

[dguy]

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?

Talk to the guys at the counter, and order exactly what you want.  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.

It wouldn't surprise me if the guy I was speaking with was talking about what he had on the shelf.  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.
