Here's a cut and paste from Dan's instructions, which are located on his website. http://www.diehlaero.com/ . He has underlined MUST in the instructions.
KR-2 LANDING GEAR INSTRUCTIONS The composite landing gear is made from a 3-M product called Scotchply. The castings are made of aluminum alloy. The prototype was load tested to 2.5 G's, 1,250 lbs. On each main gear. This resulted in a 3 1/2" flexure which is 75% of ultimate bending. With this information and subsequent flight testing, the gear was lengthened 4". The increased leg length provides more ground clearance. To 3/4". This has resulted in a nice springy 3 G gear. Also, at this same time the gear legs were beefed up, the casting thickness was increased by 3/32". The Gear legs are shipped precut and the edges are chamfered. The taildragger conversion mounts the main gear on the forward side of the main spar with castings bolted on just outside the fuselage sides. The gear legs angle forward. The tri-gear mounts the gear legs on the aft side of the main spar with the legs angling back. The tail dragger version of the gear leg has a straight leading edge from top to bottom. The tri-gear version has a crook on both sides of the leg. The arrow points forward. Four pieces of biaxial cloth are provided with each kit. This cloth must be put on the legs before drilling holes. The cloth runs from top to bottom of each leg. Follow drawings. This cloth is installed to prevent leg twist during touchdown and braking. After the biaxial wraps have been installed, the brakeline housing needs to be built. Either Epoxy or vinylester resin will work fine. To enclose the brakeline, a large diameter soda straw can be "hot glued" to the edge of the gear leg below where it bolts to the casting. Once attached, two layers of fiberglass should be wrapped around the straw. This holds the straw in place and helps "fair the leg". (Note: On tri-gear versions, mount the straw on the forward side of the gear. On the tail dragger version, mount the straw on the aft side of the leg. Six AN-4-32A bolts mount the main casting to the spar. Two AN-4-16A and two AN-4-17A bolts join the leg to main casting. The axle casting is bolted to the leg with four AN-4-15A bolts. The axle is bolted to the axle casting with four AN4 bolts. (Not provided in kit.) The length will vary depending on the axle and type of brake available. Cleveland and Matco are the most common.
