Axle offset measurement ('68 vs '70 C10)?
I'm planning for rear disk brake conversion (5th Gen SS) on my '68 C10, and wondering if the axle FLANGE and axle OFFSET are the same for '68 vs '70? My '68 C10 is out west, but I have a '70 C10 roller frame here in NY I can look at. Would the axle offset be the same? and is the flange pattern the same?
I am not 100% sure these measurements are correct for a '68, can someone confirm? Some background: Both the '68 and '70 rear housings are original COIL spring, 8.875T differentials (12-bolt). My understanding is that the 'early' (pre-70) axle WMS to WMS is 62 1/8" and the 'late' (post-70) measurement is 63 1/2". With that said, I'm not sure if that changes the offset measurement? For the record, I am aware of the possible 'drift' issue when running disks in back on C-clip axles. I will be purchasing new axles(5 x4.75 lug), bearings, clips, etc. in hopes this will mitigate to a point of not being an issue. Thanks in advance, Kevin |
