I recently purchased my second driveshaft from Denny's Driveshaft. The first one was several years ago when I built a 1951 3600 with a 700R4 trans and a Chrysler Hemi engine. The one I just order was for a 1935 Chevy half ton tall cab pickup with a 454 engine with a 350 transmission and Camaro rear end. In both cases I talked my needs over with them and they made perfect fitting driveshafts that exceeded my expatiations. I don't know them personally but I wanted to put out the word that if you need a custom driveshaft be sure to call them, they do excellent work.
