Hoping to get some help here from folks who have installed the Guard LSD in a 915.
While mocking up the Guard LSD for my 77 915, found out I will need longer ring gear bolts. Gave Matt from Guard a call and confirmed there is a specific LSD bolt set I can buy from Porsche but he couldn't remember the exact part number and silly me I forgot to write down the number he thought it could be and I don't want to keep bothering him haha.
Looks like the ideal length would be around 25mm but I can't find any Porsche ring gear bolts that are 12x25mm long. The closest I could find is 928 332 276 03 which is 12x21mm for the stock LSD and should work for a 77 915.

Stock open diff bolts are 16mm and far too short.
Are there any 25mm options on the market people have used? I looked on ARPs site and couldn't find anything. There's lots of room so if I can get a 4mm more thread to bite per bolt, would be great.
Some pics of a stock bolt mocked up to the guard unit, stock bolt length, and length I'd like to get. any guidance is appreciated!
