Then why the discrepancy for the emergency brake cable? The one I received as a replacement was too long. The only thing I can think of may be that my car is an early car ("one of the first 10,000 Buicks made" is the saying on my original key bob). As such, it has the "short chassis" where it ends at the top of the rear wheels. This means that from this point to the rear bumper is nothing but sheet metal and two brackets supporting the bumper! Could this be the reason for the shorter cable?
