If the sequential took a plate "over" the gated plate and then was fastened with two screws. No more then four. I would be ok with that.
But the removal of one install other and rinse and repeat to switch back is rediculous.
My idea while still requires some wrenching does take out the step of removing gated plate.
So basically each time you switch. I removed taking put and replacing four bolts of the eight. Time is money errr time is game time burned.
Also assume the sequential plate would need a centering spring of sorts to be a sequential shifter. This has to be integrated into that other plate. It may be just that good that it won't be a such a hassle to change.
Either way. I can be bothered to change some bolts. Easier then swapping real trans. Let alone easier then a shifter swap.
