so , I found a really competent guy , Pat Mescher , at Bill’s Speedometer ( bills.speedometer@xxxxxxxxx) , Excellent interaction with him , second generation guy doing this . I was chasing 37 packard issues , but got into discussion with him about things I had found wrong on 300’s , especially tachs that are a joke . I have been into 5-6 F,G tachs maybe 10 speedos , most frustrating thing there is in a 300 to work on . He pointed out to me that older units — (generally pre our cars ) had a jewel bearing in bottom where input shaft spins around the lower end “point” or tip of needle mount , but later it is just a drilled hole in the brass ( low quality junk) This is like jeweled bearings in a watch , or lack there of . No amount of “ rebuild “ fixes that once chewed up , my exact experience on my own work , needle bounces around more or less as bearing surfaces at bottom of hole are shot . Tip is about as big as a hair . Crap shoot what you get . I stopped bothering , never works right once used So he says with some effort he takes it all the way down to that level , maybe he can put a jeweled bearing in , has done that , I am thinking especially tach . Turns all the time fast , this happens very soon in miles . I was impressed how nice the packard speedo works compared to 300 before i broke the spiral spring ( slipped out of hand on bench )—- no dancing, nice steady reading etc — yet same design as ours ( Autolight I think ) But quality bearing in there . He says 37 are beautiful reliable dependable units . Even odo wheels are metal . Maybe SW ? ??? looks the same in any event Have not done this yet , the tach, no need but maybe someone else steps up . No firm number but 350 area mentioned . Worth it to have a really good speedo or good tach . I have spent days on these, half the time it ends a total waste . 350 is a deal . Throwing this out there , fair . Others quoted me 500 to fix speedo , with an attitude . You get it We support the good guys!
