    Just a heads up everyone, bought a set of rear Bilstein shocks(BSN-24-009294) for the Lark today from Summit. Low & behold Bilstein does not include the upper shock bolts. Just the lower nut & washer.

    Talked to Summit rep who in turn talked to the Bilstein rep who confirmed that the bolts were not lost, they are not included.

    Cheap bastards:mad:!!

    I know the size of the bolts can anyone verify the length of the bolt? I’ll get a set of grade 8 hardware from Fastenal tomorrow.

    The factory shocks used 5/16 bolts. However,I have seen a lot of aftermarket shocks that use 3/8” bolts. If the T-bar at the end of the shock has the larger 3/8” holes,I would suggest getting 3/8” bolts,and drilling the existing hole in the frame to 3/8”. I get bolts that are 1 1/4” long. Something that will allow for a washer against the head,then a lock washer and nut,or washer and locknut.

    Thanks Brian.

    Of course I blanked & forgot Fastenal is closed on the weekends. Tried to get grade 8 at Home Depot, the sizes I guessed it all sold out.

    Got grade 5 with flats, & locks. Should be okay for a bit.

    A flange bolt with a serrated flange nut will make life much easier, need to hold the bolt on the top,..
