Unfort. I do not have part no, but will try to find out from my AME and let you know.

thanks

the factory "heavy duty nose gear shock strut assembly" has several differences from the stock.  The major difference it the wider fork which is not cast but formed from heavy plate and is bolted to the end of the strut tube rather than directly pressed onto the strut tube as on the standard version.   you would need the inner strut tube and pressed on bolt type end plus the fork, and several assorted bolts spacers,etc (and the larger tire, wheel and axle hardware) last time i checked, none of these were available from the factory anymore.  however,  check out  airglas.com in alaska for an stc kit which has all of the above..you can go up to a 8.50-6 on this fork!  (pricey but availbale)  good luck  steve vw

You want the Landis/Airglas nose fork...will take up to an 8:50 tire
