you probably know all of this from reading the above posts...but here's the point im at with my interior too.....
ok, it seems that in 70, there was only one blue listed on interior colors...Thunder Blue Poly (gloss and Suede version)... after trying to cross reference the old Ditzler paint code through DuPont (which is supposed to be exact-BUT was WAY off - looked like black almost) I stumbled upon the website listed above:
http://www.tcpglobal.com/aclchip.aspx?image=1970-plymouth-pg02.jpgthis was the missing 1970 paint code page I was looking for...I have them for 71 and 71 shows two different blues on the interior...on this 70 chart you'll only find one #13848 (suede finish)...the gloss version has a different number, but its the same color...Roger Gibson has told me that it is near impossible to get a suede paint anymore, so a dusting technique is needed....
ANYWAY! I ordered a quart of the Tunder Blue Poly, and it sure looks like what I've been searching for... I will shoot this soon, and take pics for you... B5 interior needs an entire website dedicated to the subject...there is nothing out there... the door panels, kick panels, and console, are kind of a mystery....I'm using Legendary interior bright blue parts...which sure seem like they are correct...now for the horn pad, thats up n the air...it should match the dash...I have heard that "just dashes" restores them the correct blue....
On the 70 chart you'll see another paint code for consoles (Majesty Blue) listed under Plymouth Valiant...I dont know what this blue looks like yet....
71 charts list a Medium Blue Poly, and Bright Blue Poly....but this 70 chart shows everything painted with one color....just that the headliner mouldings are gloss....the dash, A pillar covers, hinge seat covers, dash corners, etc. are all suede finish Thunder Blue Poly...?!
