I have a 69 X55 car, I re did the whole front end. I need to know what size the bolts have to be or what size I can use to replace the old ones. I ordered a set from Heartbeatcity and all 4 of them are the same size, I thought there was 2 shorter ones and 2 longer ones for the back. The passenger side back back does not even make it through the whole for the nut to go on. The new bolts are all the same size.

Can anyone lead me to the right bolts and nuts?

Thanks
