I'm still looking at replacing all of my rusty brake lines on my 2000 regular cab, long bed, 5.3. The lines running between the abs module and the engine compartment (4 lines) look like they will be difficult.

I found a place that has pre-bent line kits for SOME late model Silverado's. They've duplicated these for folks who could afford the down time, and sent them the lines from their truck. They don't know which other model/years, if any, they would fit.

Does anyone know how I can find out which other year/model/engine combos would have EXACTLY the same brake lines as mine, for the lines running between the engine compartment and abs module? I guess I could try to make some measurements on other trucks. But I'm afraid I'll miss some subtle difference.

try these:

Aren't those just to replace the original rubber portions of the brake lines?
