I do supply decals for Giuliettas tho not water slide type. Mine are vinyl stickers that are printed for me by an outdoor sign company. Most of the original "decals" on Giuliettas were stickers or paint stamps rather than water slides.
Attached is my Decal positioning guide which gives some idea of what and where decals were originally used. No individual car used them all. "off the rack" parts suppliers made sure that no two Giuliettas are quite alike.
If you are further interested in decals for your car contact me off list or with a PM, I keep all of them in stock for my own restorations.
