Spyder Drive shaft Bolt sizes

PostPost by: cliveyboy » Sat Mar 11, 2023 9:09 am

Does anyone know the part numbers (or have a set to measure) for the AN bolts on the Spyder CV drive shafts.
I am missing the bolts and Spyder are not replying to my emails.
Spyder only quote general sizes on there website, so before I start stripping the car down to measure up can anyone help.
The bolts through the rotorflexs I size as AN7-27. But trying to measure the other parts on the car are giving me discrepancy's.

Hi

Do you mean the ones that come as part of the Spyder conversion using the 7" Cosworth/Granada style differential? If so I can measure mine, I did one side today, and have the other side to fit still.....

Thanks

Berni
Zetec+ 2 under const, also 130S. And another 130S for complete restoration. Previously Racing green +2s with green tints. Yellow +2 and a couple of others, all missed. Great to be back 04/11/2021 although its all starting to get a bit out of control.

Hi Berni
Its their CV Drive shaft conversion for a standard Elan that retains one Rotoflex.
I can only see mention of one drive shaft conversion kit on their website.
Spyder quote
6 Shear bolts, plated 7/16″ UNF x 3.2″ long x 2.5″ shank c/w washers, table 3 heavy pattern and Nyloc nuts, T-type.
6 Shear bolts, plated 7/16″ UNF x 3″ long x 2.2″ shank c/w washers, table 3 heavy pattern and Nyloc nuts, T-type.
6 Shear bolts, plated 7/16″ UNF x 1.8″ long x 1.0″ shank c/w washers, table 3 heavy pattern and Nyloc nuts, T-type
I am trying to figure if I go up or down a size as AN shank lengths fall either side of the general quoted lengths.
