The E-700 Lifting Eye has-
5/8"-18NF-3 Threads from the bottom to 5/8" up the shaft.
1/8" of transition from 5/8-18 threaded dia to 3/4" dia.
3/4" to 1 9/16" up the shaft the dia is 3/4"
Starting at the 1 9/16" point there is a flange about 1 1/8" dia by 1/8" tall and then a ring 1/2' thick with an OD of 1 3/4" and an ID of 3/4".
Above that is a large loop made from 1/2" dia bar 1 1/8"radius on the OD, 7/8"radius on the ID for the top and bottom circles of the loop with overall length of 4 1/4" top to bottom of the loop. The loop is made in 2 pcs and welded together installed in the eye of the threaded eyebolt discussed above.
Good luck.
We have lifted using a strap under the upper engine mounts where it attaches to the firewall.
