I got whatever you need on that. The places you're going to need is this place for the research: Vintage Mongoose - The complete history of your old Mongoose bmx

As far as decals: https://www.bmxproducts.com/collecti...ecals-and-sets and https://porkchopbmx.com/decals-stick...ngoose-decals/

As far as powder coating bmx bikes, the recognized expert is https://www.c4labspc.com/

And parts, I go to either ebay, craigslist, the classifieds at www.bmxmuseum.com, www.porkchopbmx.com, or www.bmxguru.com.

For restoration reference go to the bikes section of bmxmuseum and find a pristine example of one, there's no shortage. As far as decals, if you can't find some, there are a few guys on there that can point you in the right direction on that.
