peetee, you probably don't care at this late stage, but it isn't a good idea to chrome plate springs. Chrome plating causes hydrogen embrittlement of the surface of the steel, and because springs have extremely high surface stresses, they are likely to crack and break when fully compressed. There is a way to post-treat them to overcome this - it involves holding them for some hours at an elevated temperature.
To illustrate the point, long ago my father had a Henderson 4 cylinder in line motorcycle. (I did say it was long ago - it was a modern machine at the time.) The bike was designed to have no cover over the valve springs and tappets, so he decided he needed to have the springs chrome-plated. Having done so, he ran a standing quarter mile, just once. The run was slower than normal, and at the end of it he found out why: 5 of the 8 valve springs were broken, from that single run.
Here is approximately what the bike looked like (I don't know the actual model year):
