Hello, I just bought a 1999 wr400f. I am fixing it up and making it street legal. My question is, does any body make nice looking billet rear axle adjusting blocks for it? Every time I search all I can find are ones for 2002 on up 426/450. The OEM part number is 5FT-25388-00-00 which fits 99-01 yz125/250,WR/YZ 400/426 and 01 YZ250F. However starting in 02 WR/YZ426-450 and YZ126/250's use OEM 5YN-25388-00-00 axle blocks. I am not sure what the difference is or if they will even work on my 1999 WR400?
