MG MGA - Introduction & Distibutor Question
Hello All. After spending a little time on this BBS, I thought I better introduce myself. My name is Bruce and I've recently joined the "MGA Proud Owners Club". I can only say "where have these little cars been all my life. Hmmm�.. I�ve done my stint with push pull or drag vehicles then graduated to Muscle Cars, then �up� to luxury cars, finally losing interest in cars altogether, with the new cars all looking very �blah�, they go from A to B, and they look like every other vehicle on the road, what�s the point! One evening this summer I googled �MG� (thinking about a buddy in high school who had an MGB). There it was, MY NEW CAR! A gorgeous MGA. I can�t believe I�ve never seen or heard of one before, perhaps my automobile tastes are maturing and I�ve finally seen the light, maybe it�s a middle age crisis. For what ever the reason ...I�m in love. (there I�ve said it and I�m not scared any more). The more likely reason for the epiphany is at my age I�m sitting up a lot higher on a fat wallet and I can see for miles and miles. It didn�t take me long to gather up some up that hard earned cash and buy myself a new MGA, and bring her home, all 37 boxes of her. I�m serious about being in love, and I can�t wait to drive wherever, in my MGA. I look forward to turning each bolt back together on her classic frame, soothing out the wrinkles in her beautiful curves, and putting the roar back under her bonnet. I hope I have time for a quick question (first of many, I�m sure): My car is a 58 with a 1600 motor and I would like to install a pertronix ignition into a DM2 distributor 40510A. I get conflicting information about which pertinix number is the right one for this distibutor. ie: LU142A or LU149 . Another sight give 2 different numbers, one for early DM2 one for late DM2, is mine early or late? Anyone know what the proper number for this application is? Thanks for listening -Bruce ![]() |

Nice start Bruce. As for the distributor, my advice would be to contact Jeff at Advanced Distributors http://www.advanceddistributors.com/ about rebuilding your unit and installing the Petronix ignition system. You'll probably save a few bucks over the price of a new Petronix distributor and know that the advance curve is the best for your car as well as Jeff sets and tests the curves on all the distributors he builds. |

Bruce, Welome to the MGA world. It's great! I thought the only variation for the Petronix is whether you have positive or negative ground. Both are sold. Regards, Gerry |

Bruce Welcome to the fold. Hardly a problem goes unsolved. I have the Pertronix (Ignitor in the UK) on my reserve DM2. Negative earth it's the LUI49 Steve |

Quite amusing actually. If you search the DM2 40510A on the Lucas database it comes up with the Donald Healey Sportsboat 1957-58! The 40510B, however, is listed for the 1956-59 MGA 1500, 1959-62 MGA 1600, Lotus MK IX, and 1955-56 MG Magnette ZA See here: http://www.mgaroadster.co.uk/lucas.pdf 2/3 of the way down page 5. Steve |

Welcome Bruce - 37 boxes - wow you were brave to take it on - hope it was all complete. Good luck in the assembly - please post photos of your progress - cheers Cam |

Thanks for the input guys. Steve, Lots of good info there. Interesting that a 40510A would show up as a boat, at least it�s a �sportsboat�. With the other specs the same, I would guess that 40510A and 40510B are close enough so as to not worry about it. and according to this site http://www.vintageperformance.com/retrorockets/lucas.htm the late version is the one I�m looking for so the LU-149 looks like the correct one for me. Funny thing, each reference show rotation opposite to each other�.hmmm. I suppose later on I can upgrade to a �full fledge� electronic distributor and keep my DM2 as a spare. But for now this will have to do. �37 boxes�, well actually I have them sorted down to 8 large plastic bins and bits piled in the attic. Cheers Bruce |

By coincidence, there is an article on AH speed boats and their engines in last month's Enjoying MG magazine (from MG Owners Club). Peter. |

Bruce Just had another look at my original DM2. Donald Healey must have had a lot of spare 40510A units for his sports boats. Mine is the same! Steve |
Steve Gyles |
Mine is also 40510A. |
