I'm about to install a pair of new longer passenger-side YJ e-brake cables into my TJ and am just curious if I'll have any issues to deal with. Are they an exact replacement but just longer than my TJ cables? I'm replacing the stock cables because they're too short for the amount of lift my TJ has and are limiting the rear axle droop. TIA!

You should be able to make the rear 2 e brake cables adapt to the front one. You should, also, know that YJ's used at least 2 different length cables depending on years. My 88 had different cables than my 93.
