Motor mounts

Phillip,
If you are using a mobile device, it's very difficult on CCfan. The best is from a home computer or laptop. Go to "post reply" or click on the "full reply editor" (diagonal arrow above). Then click on the tree with the up arrow icon. This will bring up a browse box allowing you to select the desired off your computer. Give it a try and report back.

Welcome. What year mustang. LA318 ?
You probably want to cleanup and paint those mounts anyway so pulling lags does make sense , fill and retap holes same location
If you remove motor every weekend, I do see a way on mine without removing lags
Front mount remove large nut on top of large center bolt,
Rear remove large nut under mount and pull large bolt up and out
Both mount have a sideways cantilever eye bolt that lifts off those large bolts

You need to pull lags in stringers if your restoring Or removing first time check the wood under lags

Philip,
I noticed no one welcomed you to CCfan so, welcome. How about some pictures of the project.

Have you been able to figure out what the hole is for next to the oil pan flange? Is it blind?

I need to pull the Chrysler engine out of a mustang what part of the motor mounts
Do I remove. Philip
