Unless it's a late model 7040, the rear clutch pack bolts that retain the gear are 3/8" diameter.....I'd hate to use it in an 8050FWA, but it should fit and work without a problem. Use the valve off of the 8050..much better design. All gear ratios in the PST are the same. Take a look at the way the FWA side frames bolt to the front of the bellhousing under the oil pan on the 8050......there might be a couple holes that a 7040 doesn't have??? look and be sure.

Thank You very much this tractor is a 2 wheel drive so bolt size should not be a problem
