If anyone decides to buy multiples, please resell at a fair price-

I had a pain trying to get 2, 1 I lost and 1 as a future spare. Thought this might help someone in the future.
 
so these are the nuts that hold the IP to the front cover, correct? I am glad they made them 12 PT, my 93 is 6pt and there is very few angles it will go on.
 
Yep, swapping out those 6 pt to 12 pt is a nice little improvement. Ya! Peninsular for a fair price and having them. The local Hummer/AMG stealership here is a Caddy dealer at the price I mentioned. Hopefully Peninsular keeps their price reasonable.
 
Sorry ...where i can buy from peninsular
need a set of these nuts
my problem is to find them and ship oversea...as i live in Italy
 
unfortunately Peninsular (Unique Diesel) price for this nut rise to 5.62 each ....but better than Ebay price for a gm part 9.95 each...
but this is price for nuts only...now must know the shipping rate to Italy
 
The guy John of Unique Diesel is a knowledgeable guy. Add him to your contact list.
Keep reading this forum and you’ll find info on him and others.

Welcome to the forum btw. Start a thread about your ride please. We all like to see others toys!
 
Find some Ducati / Aprilia titanium nuts CNC machined from solid Gr5 Titanium at same price here in Italy

M10 grade 8 torque 50 Nm ... M10 Gr5 Titanium 57 Nm ...as titanium Gr5 has more torque value ....i think it will be fine for application
 
Glad you were able to find what you needed locally. My main source for unique fasteners is McMaster-Carr but, for 12 pnt. flange, no Metric offerings. Price wasn't bad at less than $3. ea but, shipping to Italy would kill most US deals. Still better than $9.95 on E-Bay or $12ea on Amazon.
