Motor mount dimensions

[BlueJeeper]

Could someone with a stock TJ motor mount laying around give me the dimensions of the footprint of the mount, as well as the distance on center between the two fastener locations in the mount? TIA.

The base is 2.280 wide x 4.480 long

The fasteners are stud and hole for a through bolt and are 3.465 on center.

The hole is .440 in diameter and the stud is .390 in diameter.

That would be a 10 mm bolt and a 11.5 mm clearance hole.

Wow, thanks for the precise measurements. Is that buried in the FSM somewhere, or do you have some sort of digital calipers?

Oh, did you want me to use the digital ones? Hold on-

2.294 wide x 4.486 long

3.465 c to c on the stud to hole

stud .390

hole .4395

The digital ones also do mm's, do you need those also?

I was trying to figure out why the length changes. It's a two piece mount and the safety cover over the rubber part interfers with the OA dimension.

The width changes depending on where you measure it. At one end it is 2.288 to 2.306 in the middle.

Thanx, that'll do.
