i've got a couple of numbers off of my 10 bolt axle and i was wondering if they ment anything. these #'s are on the drivers side 217 1A 2375 253X passenger side the # is 44-1. can any one tell me if they mean anything. cowboy
Rick, Could the number on the driver's side be "IA" not "1A"? The only number I found that comes close to the number you listed indicates that an IA is a 4.57 ratio.
i'll have to check on the #. i'll get back to you soon as possible. when i rev my engine it starts to backfire when i get abotu 3500 to 4000rpm. is this just my timing? i need to time it. thanks for the help. cowboy
Hey, The 44-1 number might indicate that it is a Dana 44 axle. It's a ten bolt (at least mine is, but it's a front axle). Check a place called www.drivetrain.com and they will have pictures of the different axles or at least the covers. If you can match one up with yours by the bolt pattern and spacing then at least you'll know what it brand it is. My 65 4x4 is stock and it came with GM Corporate 12 bolt truck axle in the rear and a Spicer/Dana 44 in the front. Hope this helps.
