Click to view attachment Holes,he said,in a 914?
Part of the process of stamping and resistance welding of a unibody chassis.
The thin flat sheet is die bumped a few times to produce stiffening topography which needs'stretch'areas,avoiding tearing.
The sheet is punched with holes initally to accommodate the high stretch areas and to register in the secondary or subsequent dies.
Each high cycle die is a capital expenditure,so to minimize the number of operations,functions like piercing and trimming are combined.
The mapping out of the discrete panels is a lot like origami in metal,fully cadcam for the last 40+ yrs.
Karmann GmbH likely subcontracted the diesets to the best bidder locally,using the then new nc machine tools from mill builders.
From 1965,the steady improvements in the use of the new automation developments meant that jigging and fixturing were improved,reducing build tolerances.
Filling the holes with a rib stiffened panel would make it better.It is ugly,it appears,the fiend FeO disappearing the nether regions of the chassis.
Speaking of better,here are your floorpan panels to make repairs and replacement.

A guy could make a buck,selling for a good markup,the demand here in North America significant.
A boxful of engines,would turn a neat profit,exploiting the abundance of spares stashed away.
Financing of major repairs to the 914 could thus be effected,at reasonable cost.
Heck,if you find the 2L timed out,why the 2.5L+ V8 may be a viable selection,the repair costs similar.
A Tatra engined 914 would be unique in the world,and fitting too.A simple adapter plate to marry it to the 914 tx.
I've spent considerable time studying the proposition,the aircooled 603/613/700 a good fit.
