Scale Aircraft Conversions specializes in providing aftermarket/replacement landing gear made of white metal. This particular set is of the recently released 1/48 Hs 129 B-2/3 from Takom.
The set includes two main landing gear struts, four sets of brackets to mount the landing gear struts to the landing gear wheel well, a two-part tail wheel (yoke and spinner) plus a foot-rest to help the pilot to climb on the wing to board the cockpit.
All parts are straight drop-in replacement parts, so no modification should be necessary. You can see from the pictures the parts are very cleanly molded and formed, with no visible molding lines.
Some parts will need to be released from their casting frames and instructions on how to work with white metal parts (detaching, handling, painting, safety, etc.) are available at https://scaleaircraftconversions.com/using-white-metal/
