I'm going to dissent here. After having sudden death with a "high quality" aftermarket electronic distributor, I have switched back to points on my 1972 Cheyenne.
On Ebay, there are scores of NOS Delco points, condensers, caps and rotors to make your original distributor work as well as it did new. DO NOT use the currently available offshore electrical parts. They will leave you stranded, or offer overall poor performance.
