I agree with Gary. I'm currently using the original linkage with my T5 and it is doing well. Just make sure your bushings are in good shape. The bearing used on Jim's car is a Mcleod product. The bearing alone runs about $400.00. It is probably the cleanest way to go because a clutch fork is not required. Is the extra room worth that much to you?
And, that's just one option. There may be other, cheaper options.
One easy way to gain a little more room is to remove the shift arms from the lower end of the column, if yours was equipped and you have not done it yet. I was actually surprised at the room gained when I removed mine. It's not much but it is something.
