Well everything fit nicely on my 4th gen rear except the t-block. Now the lines reach it and it plugs into the line that runs underneath the car just fine. Problem is when I try to plug the axle lines into the t-block with the fittings, even with them all the way flush with the t-block, the lines are still loose and spin freely. Any ideas? Or do I just need to get 91 camaro axle lines?

 

The problem is that your third gen lines and the stock 4th gen lines are flared differently at the T-block. Your lines are bubble flare, 4th gen lines are inverted flare and they won't work with each other. It's an all or nothing thing, you need all 3rd gen lines or all 4th gen lines, or a custom line with the right fittings. I know the differences and can supply you with a line that will work, LMK.
