Any database about part interchange, I been reading posts and found some parts. Since all I find is used (junked) II. So any ideas. thanks

 

Not certain if anyone has built a specific database on all the parts. Any vehicle would have approximately 30K individual parts. But, I am overhauling a ‘98 D1 and when I look at parts via eBay you can see which parts are specific to a certain range of vehicle. Look up the parts on eBay you are wanting and see if there is interchangeability. Keep in mind, and if you do a broad Wiki search on the D2, there were over 400 upgrades from D1

 

All kinds of parts interchange. Just depends on the part itself.
