If you don't have any luck with leads, there are specialty companies that manufacture drawer fronts specifically for Ikea cabinets, and they may be able to replicate what you need.

Did you ever adjust your drawers to your satisfaction? I have just assembled my second 4 drawer 48" wide Ikea Godmorgon sink cabinet. I can identify two of the three mechanisms for adjusting the drawer fronts, but the one I can't identify is the one I need to adjust. The picture has an arrow pointing to under the front right of the drawer but nothing I can see on the glide looks remotely like the zoomed in illustration - I can't even identify the mechanism. The first cabinet (same cabinet, different exterior color/finish) I assembled (15 months ago) went together with the drawers aligned nearly perfectly - well enough to use without adjustment, but this second cabinet definitely requires tweaking. The cabinet/sink is mounted on the wall already and everything is plumb/level. I rarely have problems with alignment when assembling Ikea products, especially the better products - I assembled an entire kitchen's worth of cabinets 12 year ago and several other rooms of Ikea furniture, as well as Ikea furniture for friends and family), so this is really frustrating me.

The front edge to the middle of the first hole in the cabinet is 3/4 of an inch.

Out of stock, like discontinued? Or just temporarily out of stock?
