Consolidated posting for my discerning D90 brethren who own a Disco or can find use for some of these items. Most big items are pickup in/around NoVA or faciltiated transhipment via RURR. Cash or paypal (ray.gerber(at)gmail.com):
-D1 SD (High) roof rack + LR OEM ladder $550
Had it one of my trucks since 2007. Rack has been wheeled, has nudged trees as truck leaned sideways, has had (ex)girlfriends run it into parking garages when she didn't realize the max height meant max height. Survived it all and still looks pretty damn good. Powdercoating is long gone, when I pulled it off the truck a few weeks ago I hit the small surface rust with a wire wheel, rust killing primer, and hit it with paint again. Pic shows it on my truck, note no flooring/vhf antenna/lights/boxes/etc included. Complete hardware including both the stock vertical bolts (allen wrench) and SS hex head bolts. LR OEM ladder included, has some surface rust on top step. Hardware for that is included absent the rivnuts; personally I'd go with a different solution.
XD skid plate: $150
Safety Devices (?) skid plate that came stock on the XD. Stout 2 piece design. Came off a NJ/NY truck so powdercoating was toast, but only surface rust to contend with. Most hardware (missing one bolt, I'd replace all with grade 8 stuff from your local TSC). Note this will likely not work on a Defender b/c of the steering setup.
Parts grab bag (box): $50 shipped
A USPS flat rate box filled with random stuff inherited when the parts truck was signed over. Brake switch (a must for those that have such a thing), stock spare brake lines (good for when yours are trashed by a stump, will get you home), MAF for the GEMs in all of us, fuel filter, U joints x 2 to keep the rear DS in the fight, DS bolts for when it won't come off to put the u joints on, and an assortment of clamps for various hoses/fittings under a Rover's hood.
50th Anniv metal badge: $20 shipped
Pulled this off a 97...manufactured in 96...so I couldn't fathom it being on the truck other than the feeling of celebration associated with LR's 50th anniversary. Suitable for anyone with a 98, or a like feeling. Paint was toast so I stripped it. Started to repaint and then decided that the new owner may prefer something custom/kustom/whatever so I stopped. Hard to find CONUS.
AB fuel filter kit: $25 shipped
In the spares box with the parts truck, this converts the fuel filter from the always painful union setup to one with hose clamps. ~$35 from AB (I think) plus S&H, this is NIB at $10 less.
I have more stuff that I'll be posting as time goes on, if there is something you need that a 97 D1 might have, let me know.
