Rear freeze plug leaking

Welcome to 2CarPros.

From experience, I am going to say no. These things are so specific for the vehicles, I know you will have trouble if it even runs.

If you decide to replace the freeze plug, here are the directions. I realize location is everything, but I thought this may help.

REMOVAL
1. Using a blunt tool such as a drift or a screwdriver and a hammer, strike the bottom edge of the cup plug.
2. With the cup plug rotated, grasp firmly with pliers or other suitable. Tool and remove plug.

NOTE: Thoroughly clean inside of cup plug hole in cylinder block or head. Be sure to remove old sealer. Be certain the new plug is cleaned of all oil or grease.

INSTALLATION
1. Coat edges of plug and core hole with Mopar (R) Gasket Maker, or equivalent.

CAUTION: DO NOT drive cup plug into the casting, as restricted coolant flow can result and cause serious engine problems.

2. Using proper plug drive, drive cup plug into hole. The sharp edge of the plug should be at least 0.50 mm (0.020 inch) inside the lead-in chamfer.
3. It is not necessary to wait for curing of the sealant. The cooling system can be filled and the vehicle placed in service immediately.
