2bbl to 4 bbl linkage tips.

I am getting a 68 satellite, and it is a complete virgin unmolested car. 318 with a 904. The plan is to build a mild 350-375 hp 360with an Edelbrock RPM performer intake and a TQ carb. I am hearing stories that there is no 4 bbl kick down brackets or linkage available for this car and that i have to go with a floor shifter and a full manual valve body?

If this is the case, i will leave it a stock 318 2 bbl and just drive it. Any help would be appreciated.
If I may make my opinion. If it's an all orginal unmolested car why not use the original engine and build the 318? 318s can be made pretty powerful and then it would still be original. Minus the 4 bbl of course.
