andre,I would definitley do the twin stick conversion since it's apart and it's a matter of making a shifter after grinding the shift rail,nice article in this months Crawl mag,about using shifter cables instead of hard linkage lines for twin sticks,3 sticks etc.etc.
Gives the option of mounting the actual shifters about any where.



Are sure about this?I just looked under my blazer,the stock adapter for it has the normal chevy 4 bolt pattern at the tranny (th700) and has a 6 bolt pattern at the TC-2bolts per side plus 1 at the top and 1 at the bottom.
Just some more info.
