Hello,
Unfortunately, we do not carry an exact match for your original sweep that would insert into the opening at the bottom of the frame. With that being said, we do offer the 36" long 58-176 wrap-around sweep that attaches to the sides of 1-3/4" thick doors with screws. It can also be cut down to size using something like the 75-023A hacksaw.
We also offer the 36" long 40-001 sweep that attaches to one side of the door. We can't make any guarantees but review the specifications of both options to see if one of these parts could work for your repair. If not, your best bet would be to reach out to Pella or one of their dealers directly to determine if an exact replacement is still available. Thank you.
