Anyone using a Hamilton Intakes T5 adapter?

Anyone using one of these adapters with an S10 T5 behind a SBC ? I'm weighing all of the install options, spacer adapter vs cutting or changing out the input shaft. I like the idea of being able to swap in another S10 T5 if I need to without having to modify another trans. Any feedback or advice appreciated.

I haven't seen or used one before but I bookmarked the link as that looks like the right way to fix a common problem.

No mods to the input shaft means that if you happen to break a trans you can pick another one, put it in and go without hunting down a machine shop or having to modify it yourself. It also saves fighting with the issues that surround changing to a bellhousing that matches the trans and then trying to figure out clutch linkage again.
