My question is: Does NAPA carry the points and rotors for these flatheads and if so does anyone know the part numbers? My local store doesn't have anyone that knows how to look up that info. Thanks in advance, Jack 37RAGTOPMAN 09-17-2010 @ 5:15 AM reply profile send p.m. Senior Posts: 1958 Joined: Oct 2009 Jack NICE TRUCK, if you want to save you from some problems. THERE is a LOT MORE, than just replacing the points, since I do not know what your mechanial ability or the amount of equipment you have,take the following with a grain of salt. take the DIST off the engine and send the coil and distributer to have BOTH Rebuilt.SKIP is the only one that I know, that rebuilds the coils, were there are more persons rebuilding the distributers. you should or will need a KRW WILSON DIST ,tool to do it right, or a HEYER, or SUN TESTING EQUIPMENT [ these spin the distributer to test the timing advance and more, aids in making the engine run correctly in time, so it does not run hot if retarded to much,to ping if advanced to much,there is a vacuumn brake that you can adjust a little , but should be set up on a machine, just replacing the points might work, there are a few V8 VENDERS, that advertise in the V8 TIMES.were you can buy points and condensor.you might get lucky,,,!! hope this helps GOOD LUCK, 37RAGTOPMAN an KEEP on FORDIN, MODERN AUTO PARTS stores are only INTERESTED in FAST MOVING PARTS, This message was edited by 37RAGTOPMAN on 9-17-10 @ 5:42 AM larryb346 09-17-2010 @ 8:35 AM reply profile send p.m. Member Posts: 27 Joined: Jan 2010 I buy mine at oreilly's if you have one close. supereal 09-17-2010 @ 9:40 AM reply profile send p.m. Senior Posts: 6819 Joined: Oct 2009 We haven't been able to get both points at any of the local suppliers. They do carry one, which was used in the later engines, but not the other. If you buy a set locally, be sure that they are both the left and right hand sets. The last ones we bought came from C&G. A bit pricey at $27, but very good quality. Imported points have been showing up with defects such as poor or missing threads and grounded insulators. kubes40 09-17-2010 @ 9:47 AM reply profile send p.m. Senior Posts: 3396 Joined: Oct 2009 You can get points at Napa but, as Super has suggested, they are often of poor quailty. Missing threads is common. The rotors are of good quality. TomO 09-17-2010 @ 4:27 PM reply profile send p.m. Senior Posts: 7250 Joined: Oct 2009 The NAPA number for the points is ECH CS47, the rotor P/N is MPE FA67SB. I have not used NAPA points so I can't vouch for their quality. The last set of points that I bought came from Yesteryear Ford Pars in Michigan. He also provides a rebuilding service for the distributors. Tom fortyfordguy 09-17-2010 @ 4:42 PM reply profile send p.m. Member Posts: 27 Joined: Oct 2009 We stock all the distributor parts. Our points are USA made. The rotors are NOS. The caps are USA mfr'd on the 42-44 and nice repro on the 46-48 caps. We also keep the bushings, gaskets, spark plug wires, rubber boots, etc. VANPELT PARTS & SERVICE Cincinnati, Ohio www.flatheadv8.com 47Jack 09-17-2010 @ 5:50 PM reply profile send p.m. Member Posts: 34 Joined: Sep 2010 Thanks again guys, you are a wealth of good info. My 47 truck has a 39 engine in it. I replaced my old dome type distributor with a 59A 12127. The newer type has a authorized rebuilt sticker on it. The previous owner had it in a box of parts. This required me to get a long cam adapter that ended up being too thick. A trip to the machine shop and they shaved 3/16ths"off it and it works fine. The points,rotor and condenser are new and purchased online through a V8 vendor listed on this site. I like to keep spares on hand and that's why I asked about NAPA part numbers. I have a 59 Ford 671 and a 63 Ford 4130 tractors and I keep spare tune up parts for them. I hate having them quit in the middle of nowhere and the spare parts are insurance. Thanks again Jack TomO 09-18-2010 @ 8:47 AM reply profile send p.m. Senior Posts: 7250 Joined: Oct 2009 It is common for good points to last over 15,000 miles in the dual point distributor. That is why we always recommend having the distributor set up on a machine by a competent operator that has lots of flathead experience. He can tell if you have a set of good points or a set that will give you problems. A good set will have the same dwell no matter what speed the distributor is run at and will not bounce at the higher speeds. An extra spring to reduce point bounce will cause the rubbing block to wear faster than normal, so correct tension is important. Tom supereal 09-18-2010 @ 10:16 AM reply profile send p.m. Senior Posts: 6819 Joined: Oct 2009 I agree with Tom regarding point life. A frequent problem we find when rebuilding distributors is excessive play in the bushings. Usually, the shaft is also worn. This produces a "wandering" dwell as the cam wobbles. Another couple of things to consider is the alignment of the point faces to gain full contact, and the condition and freedom of the advance weights. Be sure that the advance springs are intact and have the necessary strength. Finally, examine the contact between the point plate and the spring loaded terminal leading to the coil to be certain it is clean and making excellent contact. The flathead distributor is a very durable unit, but only if properly maintained, and set up on a machine by an experienced operator.
