Default TB bypass problem for lt1

I ordered the kit off from ebay for $10....It looks simple enough but the directions are for a lt1 on a camaro/firebird...and the fittings are way to small..Are the throttle bodies somehow different...I have a 1994 vette...and the parts supplied are just way too small..Thanks

I didn't know you needed a kit for this. I just removed the lines from the TB and plugged the one that goes to the top of the radiator. What else do you need?

You do not need a kit. Simply remove both lines from TB. Remove the elbow line on the passenger side entirely. Now take the line from the radiator that was connected to TB on drivers side and simply connect it to the steam pipe line on the passenger side (the side you removed the short elbow from). TADA

Two new hoses required, and buy 2 cap offs for the TB connections that are now left exposed. This is the "cleanest" way to do a bypass for your '94

These are NAPA part numbers :

(the pics I posted were from a word document that another member sent me about a year ago, so the prices may have gone up a little bit)
