Bill,

Thanks for the information on the issue. I have another "original" assembled truck that is an early '55 2nd series 3100 that has the carriage bolt slotted core support brackets. It is a 6 cylinder and is mostly assembled, although not untouched. The frame # and cab # match, so I know it is definitely a 55 truck. This extra frame I bought I was told was a '56, yet found out later it was a '58. I simply bought it so I could modify it with an IFS Monte clip, without having to completely tear apart my original '55 truck. The '58 frame did have the original V-8 motor mounts, and what I am finding out is that this frame is the one that has the core support brackets 1" further out from the cab, than the '55 location. I took the front end apart on my original truck and removed the core support to verify dimensions. It does coincide with the Assembly manual as far as the distance from "Front of Dash" line to the centerline of the core support bolts. I am totally new at this, but I had been told that the radiator mounting tabs that run vertical and attach the radiator to the core support themselves were a different offset between V-8 and the 6 cylinder, moving just the radiator up or back towards the engine (I don't know which engine has the radiator closer or further away), but that the core support was the same for both. I may be wrong, but wouldn't the core support have to be located the same distance away from the cab if the core support is not different between the V-8 and the 6 cylinder? The inner fenders and front fenders themselves have to fit the same dimension, so the distance has to be the same I would think. Your truck looks great by the way! What do you think?
