So I bought some secondhand steps for the car only to find there is no bolts included!!! Does anyone have any or knowledge of where to get them

Just check out the holes on the chassis for size ? Guessing no steps were previously fitted ... but also guessing that the captive nuts in the chassis/carrier are seriously rusted up so that even those threads/holes could (badly) need tapping out (even if they can/could be saved) ?

m8 i think...recent thread on landyzone...
