LT4 TB on a LT1?

Will a mid '90s (think its from a '95 or a '96) LT4 throttle body work on a '93 LT1? I need to know quick!

The linkage will be different. Your '93's 4L60 uses a cable for downshifts and WOT upshifts. The 4L60E, '94 up, not sure with the vette, uses an electronic signal from the PCM.

Can't say for sure, but I've read on this board that it can be done.

If you can put the BBK along side your TB to see what is involved. I was thinking along the lines of putting the '93 linkage on the '94 up stock TB.

Cool, I am thinking the linkages can be modded to work with the '93. If all else fails I can just sell it on ebay or here. Thanks man.
