the resto pack available from
GM archives has all the frame measurements, and they do have
the 58 pdf ... the shop manual is aimed at mechs who are working on specific things in a short time span, not someone who completely disassembles a truck and puts it back together months/years later
and note that the
55.2 shop manual will work better than the 54 [AD] one .... if I remember right, the fender to inner bolts all have a slightly pointy end and all the sheetmetal to sheetmetal bolts have formed on washers, sheet metal to mount points use lock washers on 'flat ended' bolts and most have separate flat washers
the body shims won't be shown anywhere because they're added as needed on assembly for fine tuning the fit, might be useful at the cowl/fender mount point, the lower fender/cab point and core support/fender point, and they're available at most FLAPS in different thicknesses - the assembly manual shows them labeled "as necessary" - other grommets and doodads are shown in the assembly manual, and are pretty much the same 55-59, the primary difference in the front clip is the hood hinges
here's a scan of the core support mounting page, same as the 58 even tho' the supports are different, note the bolts just have part numbers, which
might have dimension descriptions in the master parts book - someone put the effort into tracking down all the specs to put together the bolt kits the vendors offer, but it would not have been a simple task
