piece of crap headers - i give up
I have Hedmans on my 68 Barracuda and the passenger side goes in from the top with no fuss. The drivers side has to go in from underneath and the easiest way is to remove the steering column and unbolt the steering box move it over. Taking the column out and unbolting the steering box takes about 30 minutes. With those out of the way the drivers side header goes right in. Once inplace hold it against the block with bungie cords and bolt the steering box back up. Then bolt the header to the block and put the column back in. I bet you can install the drivers side in 1-1.5 hours following this procedure and that includes R&Ring the steering column.
