[DeTomaso] (Was Pilot Bushing Won't Budge) - Now THAT'S Increddible!!

Thanks for reminding me; the following needs to be retold every few years. 
Please note that since copper got expensive a decade ago, 'real' oilite is 
hard to find. There are three types of "oilite" and the only viable one for 
our bushings is Alloy 641 with 87-90% copper. The other two are so diluted 
with iron powder they are MAGNETIC! Matter of fact, thats how I tell if a 
bushing is real oilite or a far-east derivitive- with a small pocket magnet. The 
iron-doped alloys- especially 'Super-Oilite' with 80% iron- will wear input 
shafts worse than needle bearings. Also note- bushings for Chevys will fit 
the ZF input shaft nose, but needs a ring adapter to fit in the larger 
Cleveland crank recess- about 15 minutes work with a 6" lathe and some scrap 
steel or aluminum. In 70,000 miles, I've changed bushings three times so far. 

I get my real bronze bushings from Summit Racing- ask for one made by 
Lakewood Industries. And check it with a magnet. FWIW- J DeRyke
