no idea on the pricing since until I meet with the fab guy, he makes one that will work, then will check with the plastics guy and see how much for that for each one. so right now, just checking on this for myself and a friend who wants one and then will see about the interest and how many people might want one of them. my fab guy made shaker extensions for me for the mach 1 shaker, which I had on my 01 Bullitt, the Frankenstang. I sold about 25 of those when we made them. the fit was great. his work is great. got to be too much trouble for me for the price that people would pay for it as I prepped and painted them all to match the shaker which required three different paints to achieve the correct match. those we made three different sizes. I did the same thing with shaker extensions, i.e., made what I wanted and for my friend with a Mach...he still has his car and the extension on it. then I put it up to see the interest in how many.
I have the first one fabbed up in cardboard and have already called my fab guy and am waiting to see when he could meet me. he works all the time, I mean all the time.
