Cons:
  • poorly made
No, I would not recommend this product.

Good product in correct application

May 08, 2010
The product I relieved was of good quality. However I need a mount for a turbo 400, I think it would be a good idea to carry a "Universal type" mount much like the one I had to buy to finish up the project.
Yes, I recommend this product.

I believe the th350 and 700r4 transmission mounts are diffrent. Here are the specs on this mount if you'd like to compare to your transmission, this may help determine if this will work. * Overall thickness is nearly 1-7/8" * Metal mounting plate is 4-11/16" x 1-7/8" * Transmission bolt hole center-to-center: 3-3/4" * Crossmember bolt hole center-to-center: 1.5" * Crossmember bolt size: 7/16"-14

Speedway part number 91018016. We do not have a specific listing for everything this mount will fit. I do have the measurements of the mount, compare to your old mount or your transmission and that will help determine if it will fit. •Overall thickness is nearly 1-7/8" •Metal mounting plate is 4-11/16" x 1-7/8" •Transmission bolt hole center-to-center: 3-3/4" •Crossmember bolt hole center-to-center: 1.5" •Crossmember bolt size: 7/16"-14
