Engine Mounts - Common Stud Size
83ford11 Article No. 83-14-7ENGINE MOUNTS - FRONT - COMMON STUD SIZE (5.0L AND 3.8L ENGINES) AFTER 2/28/83
FORD 1983 THUNDERBIRD
LINCOLN-MERCURY 1983 COUGAR
In order to commonize the front engine mounts to the No. 2 crossmember fasteners between 5.0L and 3.8L engines, the stud and nut diameter was increased from 12 mm to 14 mm. Early production 3.8L engine equipped units will have the smaller 12 mm stud. However, service replacement front engine mounts will have the larger 14 mm stud.
This article outlines the procedure to be used if front engine mount replacement becomes necessary on a 3.8L vehicle built prior to 2/28/83.

8. The "teardrop" mounting holes on the No. 2
crossmember pedestal bracket must be modified 1 mm larger by filling or grinding in order for the new insulator studs to seat properly. Refer to Figure 8.
NOTE: It is recommended that a 14 mm bolt be obtained and inserted into the modified hole to be sure adequate thread clearance is available.
Installation:
1. Position the insulator and bracket assembly to the engine. Install the attaching bolts and tighten to 45-61 N-m (33-45 ft.lbs.).
