I put the Edelbrock TBI on my 93. Machine shop wanted $65 and a week to work the dist. opening. Car needed to get put together and since I was one of the first to use it, didn't know about the problem. To rectify it, I bought a truck dist. of the same vintage and then with the help of a friend, placed dist. in hole, then placed intake on. Dist. was about $100.00 but we got it running. Also, brake vac line needs to be fabbed because stock set up won't work. Fuel lines need to be tweaked slightly. Original brake vac port needs to be plugged which then interferes with upper rad hose. Made it work by grinding down head of brass fitting. And finally...unable to notice gains, if any. Others have theories on that. After I did mine, many recommended getting a 4bbl intake with Turbocity adapter. FWIW. Do a search on Edelbrock TBI, I did many replies about this and several very detailed ones about 6 years ago when I first did this.
