3-speed TO 4-speed swap?????
Will a '67 4 speed that sat behind a 6 cyl be a simple bolt in behind the 307ci in my '69 currently a 3 on the column ? Besides the cutting of the floor and removing the mess of shifting rods what other problems will I face? Thanks ahead of time for the advice!

If it's a HD 4 spd lenghts will be different and you will need high center hump ,posible spline count difference otherwise

spline count is the same. depending on wheel base of the trucks being the same , whether the drive shafts will swap. i put a hd 4 speed in my swb and had to cut the ds down because it was from a lwb. easy swap, every thing is straight foward........
