View Full Version : Differential mounting fasteners in Coupe 65 IRS

For my project, I have received the IRS for my Coupe 65 from FFR.
In the manual, it talks about the "smaller/Shorter bolts" and the larger/longer bolts", but what are these fasteners?
I don't have any prepackaged nuts and bolts with my new differential from FFR.
Are there part numbers? Description of the fasteners?

Also, while I am at it...
Though I received a box of IRS fasteners, and as I am assembling the toe adjustment arms, I can't find either of these
HHBOLT 0.6250 - 11 x 2.5 x 1.25 - N (2)
B18.2.3.4M - Hex flange screws, M14 x 2.0 x 80 - 34N (2)

FFR says they have now delivered everything. There are some similar bolts in there, but definitely not these.
I do have a local bolt shop that seems to have everything. Is the above information enough for them?
Are they graded bolts?

See if information in this thread helps. Several Factory Five responses: https://thefactoryfiveforum.com/showthread.php?47497-Differential-mounting-fasteners-in-Coupe-65-IRS

FYI, Factory Five doesn't actively monitor here in case that's what you're thinking.

Chris,

I found this as I prepare to swap my differential.

Maybe this will help.
