Guys do you know an online car parts retailer that sells Pontiac Distributor, customize Pontiac Door Handle, and Pontiac Engine Mount??? Please reply to this post if you know one... Thanks in advance!  

I bought a very nice Mallory magnetic pickup a few years ago from Summit Racing, and they do have online catalogue.  I just found PN MAA-5758001 Mallory Pontiac distributor which has magnetic pickup, billet aluminum body, small cap, and Vacuum advance for street use.  Mine has about 10,000 miles on it, and never even think about it since I set it up.  It will work with just a coil as a regular distributor, or is compatible with most hi perf ignition systems.
 As for engine mounts, I'm sure they are avail from several of the more hardware oriented linked sites to this one, and the same for door handles from such suppliers as year One, Classic Industries, or Ames performance. If you don't see them listed, email the suppliers, or call their 800 numbers and I'm sure you will get some good referrals. Good luck!
