I disagree. The DeTomaso Forum is full of unmolested-car owners that first discovered their ring gear bolts were a problem when a bolt-head appeared in their ZF drain oil! One owner bought a low-mileage car in Arizona last year and was detailing his engine compartment. He had removed the ZF to have it polished and an attack of guilt made him open up the lower cover for a look. ALL TEN BOLTS WERE BROKEN! The ring gear was wobbling around on the bolt shoulders and the bolt heads had been rattling around in there so long, they were round, not hexagonal..... I watched Wilkinson sell a guy a spare lower cover for a ZF 10 yrs ago at 'Vegas, when just after arriving from LA, the owner put his ZF in reverse to change parking spaces, and a broken bolt-head caught in the gear mesh and was spat out hard enough to break the lower cover. A gallon of hot 90-wt covers a very large area of the average parking lot.....True, not ALL ring-gear bolts will loosen or break. But to me, the risk of destroying a $6000 transaxle is matched by changing 10 known-to-often-be-defective Euro-bolts to cheaper but stronger US-made ones, and safety-wiring them correctly is simple insurance. Your choice-
Who ever told you that has NO CLUE what he or she is talking about,As I have said before the stock bolts have a seration on the backside of the head that is HARD and you have a Diff housing that is also HARD, so when you have two hard surfaces mating one smooth and one jagged and big V8 power over 30+ years one of the surfaces is going to get brittle, then you have a gap between the two,and out comes the bolts.

What's a ball-park price to get a project done? Let's say I drove my '73-L into your shop, could you safety wire it, install the taller 5th gear you're advertizing (in Spring 2003 PI issue) and polish the ZF and Bell Housing for $2,000 +/-? I have no idea. How long would it take, by appointment, when business is at a not too frantic pace? Feel free to email me a quote or post it in this Forum. Thanks.
