Driver side freeze plug behind motor mount....

[cLaWz]

Is there any way to replace this particular freeze plug without removing the motor mount? Just bought an 86 with a 305 that needs this plug replaced but theres no way I'm going to be able to get a jack under the motor safely due to how soft the ground is out on the farm it's sitting at.

Any tricks to getting one of those rubber expandable plugs in there? Would much rather get a temporary fix in place until I can drive it home and safely work on then spend the $200 on towing (Outside city limits so they want to charge a ton more... bleh)

Thanks
