Take it easy it's not rocket science just use the bell crank assembly from the later engine. After this is installed on the block and hooked to the carb it's just a simple matter of adjusting the original rod from the foot petal to the bell crank. I did this on a 46 a couple of years ago the foot petal rod had to be shortened and bent just a little just cut the rod into and vise grip it back together till you find the happy spot. When the happy spot is found cut the over lapping part of the rod off butt weld and grind till it looks like factory. I think the original spring from the old engine that mounted to the oil pan might be a little to long might need to be shortened.
