it is pointless to argue as the seller shows no intention of rectifying the situation.
but anyways i will post my pics of what i received to prove my point,
these are pics of the assortment of bolts i received.
here are 3 bolts with a short head that are 35mm in length (used for a 10mm spacer)
here are 3 bolts with a tall head that are 40mm in length (used for a 15mm spacer)
here are 10 bolts that are 35mm in length (used for a 10mm spacer)
here we have 4 bolts of the correct length 45mm
here is a stock bolt for reference 26mm
