I used a few set of the decals mentioned and had no issues with fit or scale. Its hit and miss with CA decals and often they are the only option available unless you roll your own.
In the past CA offered two different sets of decals:
One that was printed and intended to apply clearcoat over the top for protection.
and thicker but supposedly can be applied and NOT clear coated over.
If you ordered decals from them or off eBay its a crap shoot which set they actually send you.
I clear coated over mine and never had any issues.
