When I did the first ramps for the donor for molding I used Goo-Gone to remove the main decal from the original ramp. Came off very nicely, then used 3M spray glue to attach to the new ramp.

how did you use the goo-gone in the removal? did you soak it for awhile?

What I did was to soak the edge and they slowly lift it up. Then I used a small brush and while pulling up slowly continued to brush the Goo-Gone underneath it. Guessing it probably took me 15-20 minutes. Once removed, I just cleaned up any remaining glue. Really came off nicely.

Marco's has a decal set for GNR and I'm pretty sure it used to have that decal, but does not appear there now.....might be worth reaching out to them. I've seen them on Ebay in the past but not now.

Dave included these two decals ganged up on a sheet when he did his original run of G ramp repros. Not sure if he still has the art (or if he ever did - those may have been produced by someone else.) If I get a chance in the next couple weeks at work I could vector them - not that much to them.

Bay Area does have a decal sheet with those included. $60 though - tough spend if that's all you need. See: http://bayareaamusements.com/Merchant2/merchant.mvc?Screen=PROD&Product_Code=GS-GNR98
