If your SPID does not say the axel ratio, is there a default?

Attachment 1868517

The PO said he thought it was 3.73 but I'd like to know the original config.

Thanks

Re: SPID Question

If your dana 44 front differential still has its tag (bolted under one of the cover bolts) it will tell you the ratio. Obviously, the rear corporate axle would be the same.
