Hubs for my 3" 911 struts Options

[Literati914]

I have a set of early 3" 911T front struts that I need to get hubs for.. is there any chance that a set from a 911S (991 version) would work ? I found a smoking deal on 'em..

narrow body car if that matters, cookie cutter or deep six replicas being considered. TIA.

..I'm going to have to measure the front hubs on my '74 with the fuchs but eyeballing through the rim I think it's also 47mm.

Yes, please do check for me the next time you have wheels off, appreciated!

I imagine the 40's will work as well, just 7mm narrower on each side.

True, the 7mm is not a big deal for tire placement - BUT the thing is, only one hub (either 40mm or 47mm) is going to be the correct hubs for the Brembo cals/Vented rotors combo, specifically.

..The M calipers would have spacers between the halves to accommodate the vented rotors. I'm not certain about the hubs, but somehow I think that solid rotor had a different (thinner) hub.

Yes, like the Brembo rotors, which is why it's important that I get the right hub. So I was wondering which hubs the M rotored cars used.

... I did put unvented M calipers and rotors on the front of my conversion car and everything worked fine with early (non hub centric) hubs.

So, you're saying that you removed the spacers from the M calipers and used solid rotors and 36mm hubs?
