You have to replace the starter; the bolts are right on the flange type part of the starter, where the starter meets the transmisison. there is 3 bolts holding it in. they are most likely 13mm, 14mm, or 15mm bolts. but on some caravan models you have to remove the front transmission mount to get to it. this is probabally why you cant find em'. but you will have to remove the mount, then the starter bolts. then you have your starter out! but when you want to put the mount back in, you may need a floor jack to lift the engine/trans um into the right spot to put the bolt back through the rubber part. Tricky, but possible!
