Spacers for short shifters, why does the TWM kit not include them? Options

[94gts]

The TWM kit pictured on there web site does not show the spacers to raise the whole unit up even in their instructions. I've searched the forums and have been reading about the 7th gen SS instalation and noticed all of those included spacers. How does TWM accomplish this? Is it only the 7th gen shifter that requires this mod, are they that different? I have emailed TWM asking them if the shifter it's self is actually different, I'm curious to hear what they say.

The reason I ask is that we have a local (formor) TWM dealer who has 5th gen kits and 7th gen kits for a really decent price but sadly no 6th gen kits at all. He was reluctant to sell me a 7th gen shifter, probably cause he thinks I'll just try to return it if it doesn't fit. I'm sure if an e-bay 7th gen shifter fits then a TWM one will, I was just currious why it uses spacers and the 6th gen specific doesn't?
