Rob,
Those are 914 Bike Carriers with the slots for the handlebars & there were also straps to them to secure the bike handlebars. <Correction - they were hooked bolts with nuts & washers to hold down the handlebars - not straps - & went in the hole in the flat cross plate between the 2 uprights with the handlebar slots.> Mine doesn't have the extra flat plate with the 3 holes, but I'd guess it's a spacer plate of some sort (mine never needed them).
There were also 2 "C" shaped plates with slots for straps to secure the bike seats, & rubber pads glued to the inside to cushion the rear deck lid where they slipped over the outside edges (2 plates - L & R for 2 bikes). If you can't find yours, then they could be fab'ed & PC'd or painted by somebody from the originals as a pattern.
Do a search on here or at Bowlsby's site for pix of my carrier, box & installation intructions. My rack is buried in the boxes in my garage & my saved links on here were lost when Sir Andy deleted everyone's saved topics a year or so ago, and my laptoip's HDD crashed with its bookmearks & I haven't restored the pix files to it yet. Sorry.
I'll bet your Dad used to use them for his bike(s) on his 914 back in the day - as I did with mine!
They should sell better as a bike rack!
BTW - IIRC my set cost me $50-60 in the late 1970's!!
Good Luck!
Tom
