I have a 54 cab that I'm using but changing it over to 51 with split w/shield. Solid cab so thought it easier to change roof and cowl panel. Got new parts everything looks good until the upper corners are not going together real easy. the reinforcement corners at the top don't want to line up very well. I don't have an assembly manual for measurements and I'm at a cross roads trying to figure it out. Anyone tried this before that could give me some direction or would an assembly manual have answers? I figured that since post parts were listed as the same then the roof and cowl panel would change out and everything line up fairly easy. If the door frame assembly is different on 51 back but the same for 52 up 1st series then the upper attachment plate that the cross brace welds to should be the same. Roof and cowl panels show to be the same 47 up to 53 I believe.
Also, anyone had some experience with smooth firewall replacement panels...mine is good but has a load of holes in it and I thought it would be better to replace and then drill what is needed instead of welding old holes and filling. Thanks for any help and advice on this....
