Trying to change the starter. can only see 1 bolt holding the starter on. the engine side of the starter is hidden by a cross member. It has some holes that may let me see the other bolt, I’m hoping. Gonna have to jack it up higher to see. what do you think?
3.1L Engine Starter Removal
*NOTE – Upon removal of starter, note if any shims are used. They should be reinstalled in their original location during installation if shims are used.
If starter is noisy during cranking, remove one .015 inch double shim or add one .015 inch single shim to the outer bolt. If starter makes a high pitched whine after firing, add .015 inch double shims until noise ceases.

This does not help. I have a cross member (welded in) covering half the starter with a 1/2 in. clearance if I’m lucky. Should I start looking at taking the motor mounts in the front out and rocking the motor towards the rear till I can get at the rear bolt?
If you need to rock the engine, take some precautions.
1) restrict movement of the vehicle by blocking the wheels or fully support on jack stands. Park brake is an option.
2) PLACE TRANSMISSION IN NEUTRAL!!! (damage will occur if this step is skipped)
3) Then remove front engine mount and ratchet strap the engine forward
Got it done.
