It sounds like your jack may use a weld-on mounting plate like # F500277 but I pulled one from the warehouse to measure its hole spacing and found those dimensions to differ from what you mentioned. The mounting hole spacing is 3-7/8-inches x 4-1/2-inches measured on hole centers as shown in the linked photo I prepared for you.

I checked the Heritage Trailer website and found that many of their boat trailers use the excellent Fulton F2 jack # F1413050334 that uses the above mounting plate.

We do not have any jacks or jack mounts that use 2-1/2-inch vertical hole spacing; that is fairly small for most trailers. If you like you can submit a photo of your jack mount to help us identify what you need. Or if you prefer you can replace the jack with a new one of the type and capacity suited to your needs.

The linked page will show you all side-frame-mount jacks which include drop-leg, fixed-leg and pull-pin types. You can click on the filters to narrow the results to your preferred type and required weight capacity. For example, for a bolt-on side-wind jack rated for 1000-lbs you can use Pro Series # PSEJ10000101 that has a plastic caster wheel and fits trailer frames up to 3 x 5-inches.
