Chris… I think the colors are pretty close to the reference, but perhaps the scaling of the medical tapes weaving, don't match the original.
All in all the your skills and patience are amazing. Keep up the great work.
i am sure your cad model is great. But I could'nt resist the challenge, to do my own one. I converted it into STL format, which should work fine with printing. The scaling is not correct by now, but you might use it with your fantastic funny car built.
ebay seems to be a good starting point, for searching classic parts: http://www.ebay.ca/sch/sis.html?_nkw=NOS%20KB%20Keith%20Black%20Hemi%20valve%20cover%20breathers%20w%20gskts%20Dragster%20Gasser%20Top%20Fuel&_itemId=221428512163
