Dose any one still make a 6 duce set up for the nailhead or is it just the ones floating around on ebay and such. Oh any one seen that 4 duce set up on the HAMB page (jolopy journal)looks home made.http://www.jalopyjournal.com/ubbthreads/image_uploads/272099-NailMan01.jpg
I haven't checked it out for a while, but VintageSpeed.com always had 2x4's, 3x2's, 6x2's, even 2x2's and 4x2's for all sorts of engines, including buicks of course.
No 6x2s though I just talked to him about making a 4 duce set up using adapter plates on the two 4 set up
