I'm going to replace my clutch (including the pressure plate), and I'm wondering if I can re-use my old bolts, both on the PP & on the flywheel. ('69 stock 383 4bbl) I know it would be "easy" enough to do so, but I've got everything I need, except for new bolts & I'm eager to get started. OK to re-use the old bolts? Also, where would I obtain new bolts? Anyone know the sizes? Thanks.
