Re: BX axle code?
Looks like I'm showing up late to the party . Spring break and away from the computer .I should be able to clear up the rear end mystery .Lets go back to the summer of 69,we were having trouble getting the car to launch consistently,so we were at Milan dragway on a Saturday trying different methods. Well after the third launch neutral starting I shattered the origional rear end,it had a 4.56 gear from the factory,the ring and pinion ,left axle and housing were destroyed on the launch.We winched the car back on the hauler and went back to the shop. Seeing that only the right axle was salvageable we pulled the assembly out. The parts dept had a warranty axle assembly with a 4.88 posi laying on the floor . We had it installed in the car and back at the strip on Sunday morning with No Neutral Start written on the dash!So the rear end in the car is not the origional .

Re: BX axle code?
Its funny that you ask, but yes most of the racing damage was repaired under warranty claims .My friend Tom C. was the Corvette and Hiper specialist and when work was slow the race fleet was in one of his stalls.We drove the service manager crazy,he was not a race fan and didnt have any sense of humor .We were talking this morning about some of the stuff we pushed thru on a claim ticket.

Re: BX axle code?
Jeff , Did you notice the date code on your broken pinion gear June 69 ? We had 4.56,4.88,5.13 and 5.38 gears in and out of the car over the years . The 4.88s seemed to be the best combo overall.Some of the gearsets we used were the hi impact gears.Your car would have been a COPO order to get the 4.56 gears from the fsctory....Bob

A 4.56 posi would have been an RPO order. What makes you think it's anything COPO?

Re: BX axle code?
The 4.56 and 4.88 gears were ordered with RPO 84 linked to COPO 9511

So if I ordered any '69 Camaro with a 4.56 or 4.88 geared diff I would have to order a COPO option?

Re: BX axle code?
Is that also true for a 1969 Chevelle? Was there a special Copo for 4:56 gears?
