1990 F350 460 4X4. Removed bottom bolt. Around 10-11 o'clock there should be another bolt, correct? I see non. The starter moves a little but is still very firm. There is nothing else holding the starter in besides the 2 bolts correct?
There should only be two bolts if I remember.... One on the bottom and one directly across (on top) from the bottom one..
If you have both bolts out, most likely it is hanging on the thin aluminum plate between the engine and trans, it may have a burr where someone has tried to put the wrong starter on it or just messed up an install... It is a close fit, it has to be as this is what aligns the starter to the flywheel..
