Think the caliper spacing is different. 3 on one, 3.5 on the other. Others will know for sure.

Essentially, no. And it's NOT the mounting bolt spacing. The offset is different for the caliper mounting ears, and they won't center on the disc. I have heard rumor that there "may" be an interim strut in production in late '72, but I've never seen one.

I tend to think they "might" but I've never tried it and, I've been told no.

The offset on the calipers is quite a bit different. That is made up on the rotor side. SO... I "THINK" if you move rotors and calipers you "MAY" be safe.

I've also heard of the interum strut but, never seen any proof either.

I have no more 914 struts laying around, early or late, so I cannot give a definative answer but, I'd like to see EARLY ROTORS and EARLY CALIPERS on a LATE STRUT to see what happens.

I could be very wrong... all signs point to that.

instead of the unicorn strut theory - i am begining to think maybe eric is on to something - that very possibly - an early caliper and rotor can be fitted to a late strut.

before i order a set of early calipers from eric - i want to get one or both my struts replaced with a matching set of early struts - since i recently installed new rotors and bearings.

now i want to do ball joints and install rebuilt calipers as my braking is still sub-par.

i can squeal my tires under emergency braking at 60 mph but at 30 mph, if i just mildly hit the brake peddle, stoping power feels weak.

I just did re-build my front calipers and replaced 35 year old hoses this weekend. I will never again complain about 914 brakes again. Now to do the rears.

i replaced my rubber lines recently.

** if it is determined that a late strut will work with an early rotor/caliper combination, i will just need one late pass side strut.

Hmm, I just always swapped the whole thing.

But yes the only difference is 1/8" spacing difference caliper to rotor centering. I think it is add a washer going early caliper to late strut.

320I caliper to late strut is machine off 1/8"

So I might have this backwards.

new vantage point..

based on this pic - if it is off by 1/8 inch - it is not correctable by using washers.

Offset on the calipers is much greater than 1/8th"

Late strut, early calipers/rotors WONT fit.
Early strut, toss it...it has the crappy ball joint anyways.

I never bothered to try later rotors/calipers on an early strut....I replaced the early strut and went the other way.

I will be in the shop today, Eric....tell me what measurements we need, I will take a look and see what I have left.
