A friend recently acquired a '67 Corvette, which had previously been restored to a condition that satisfied the critical judges of the National Corvette Restorers Association (NCRA). I was amazed to learn that NCRA judges demand that a properly restored Vette retains imperfections that...

Does anyone have a recommendation for an antique auto radio restorer? I noticed in Hemmings that many are advertised. Dan Fults

I installed a temp gauge in my 63 409 Biscayne this weekend. Then I asked myself, "What the heck is the normal operating temp range for this engine?" Dan Fults

I'm thinking that the chance of starting an engine in a Chevy that's been sitting in Texas field for 30 years is pretty low! I've got to admire this guy for trying. Dan Fults

Many thanks. You are right. There's no excuse for laziness when it comes to brakes. I'll bleed the system completely. Dan Fults

Dear 348/409ers, I plan to replace both, front wheel cylinders on my '63 Biscayne. When I bleed the brake system afterwards, can I limit the bleeding to the front wheels or do I need to bleed the rear wheels also. What I don't know is how far air, introduced from the front, can travel...

I want to praise the new rear axle bearings I bought from Mike (1958 Delivery). They solved my oil leak problem and got my '63 Biscayne back on the road. It took the machine shop only minutes to remove the old bearings and press on the new ones. I can at last enjoy my newly rebuilt 409/425...

Thanks for recommending 348/409-er Mike (aka 1958 Delivery). I ordered a set of new bearings from him today. This pesky oil leak is preventing me from enjoying the quiet ride of my new 3.36:1 gear set.

Good observation, Blk63ss. Sadly, the leak persisted even after I replaced the O-rings.

Ah, stupid me! Now I get it. With the sealed-type bearing, there's no need for oil to leave the differential housing and reach the bearing surface.

I am trying to determine the source of my leaking rear wheel bearing in my '63 Biscayne. I suspect the oil is coming through the bearing rather than around it passed the O-rings. Looking at the bearing structure (see attached photo), I am wondering how the oil normally gets into the bearing...

I noticed in a 1967 Chevy shop manual that in positraction differentials the side gear and side gear retaining cup were not separate, but rather integrated into a single part. Whether Chevrolet engineers made this change to save money or to lower the frustration levels of mechanics has been...

I solved my problem inserting the axle shafts into my newly rebuilt positraction differential by removing the pumpkin and realigning the inner splines of the side gear and side gear retaining cup (plate) on the work bench. I failed to accomplish this with the differential in the car using the...

I think the axle shafts are not going in fully because, as Don mentioned, there is misalignment of the internal splines of the side gear with those of the clutch plate retaining cup. Professor Kelly and I had these aligned when the differential was on his work bench, but maybe there was some...

I need advice on how much force to apply when installing rear axle shafts. I replaced the pumpkin of my newly overhauled positraction differential (see "Rear Axle Master" thread) in my '63 Biscayne. The problem now is that the rear axle shafts are not seating fully, even though they engaged...
