OPTION 1: PCD-converting wheels spacers are easiest way, works OK with high-offset wheels eBay search
does not look possible to put 5-lugs in a stock hub
If you swap to B210/B310 struts
Looks like enough material to fit 5-lugs?
Until you turn the hub over
So it looks like a strut swap is best option?
OPTION 2: B310 ("Datsun 210") struts are same length as 1200, but are the larger 2" tube so your shock inserts choices are abundant. If you swap these onto your 1200, Ford 5-lug rotor-hubs from eBay bolt on. See B310 Strut Swap
and Ford Brake Swap
OPTION 3: Maybe could swap S14 "240SX" 5-lug struts with 5-on-4.5" wheel bolt pattern. See S13 Strut Swap
, should work IF S14 is similar. Uses 1200 struts with Datsun B310 lower control arms & ball joints
