Wrong forum Mike, but I believe the answer is "yes".

If you're talking about the control arms (I can't really tell what you're talking about for sure), I thought there was at least one subtle difference in the 6 and 4 control arms. CRS won't allow me to recall exactly what it is though.
Anybody? Moved to the garage.

To use the lower control arms on the '70 you'll have to use the '70 ball joint. They are different between the '70 & '74.

Mike, out of curiosity, what is there to rebuild as far as a trailing arm goes? New bushings?

If you are talking about the rear trailing arms suggest you look at Chris Foley's stuff at:
http://www.tangerineracing.com/suspension.htm#Upgraded%20Trailing%20Arms
He is an advertiser here, a poster here and does excellant work.
He did the total trick on my trailing arms and they came back straight and totally reinforced.
Really nice work.

torsion bar spline count on the 914/4 is different than 911. So if you mix and match 914/4 with 911 you must use a torsion bar that is made for that arm (spline count). I can't remember if spline count for the 914/6 matches the 914/4 or the 911. PET diagram should show if the 914/6 part is the same as the 911 part.

It is confusing as to what the OP is asking. Are we talking about front suspension (a-arm) or rear suspension (trailing arm)?

Trailing arm ....just could remember what its called ..Im on the right road now

It's also confusing because 914 rear trailing arms are also control arms. 
Like I said before, I'm pretty sure there is a subtle difference between 4 and 6 trailing arms. I think it's the e-brake mount, but I'm not 100% certain.

The arms themselves are the same.
Differences were in bolt-on components:
the brake calipers - sixes have bigger pistons;
the hubs/rotors - sixes have 5 lugs, not 4 bolts.
BTW, the stiffening on my refurbished trailing arms is lightweight and comes at no extra charge along with the straightening, powdercoating, new bearings, new bushings, and new pivot shafts.

I believe the trailing arms are the same on the 914 for all years and models (there are, of course, different left side and right side parts). At least, PET shows the same part numbers for the left and right arms of all years and models.

Mike I think you should get them done no matter what. I know if they didn't work for you? I could get them from you cheap later

Hello Chris! so your saying that I can take the set off the four banger have them rebuilt and then just bolt it up to my 6 and everything else will bolt right on...I dont want the stiffening part just the powdercoat, bearings , bushings and shafts..and zerks ..I will give you a call soon thanks

The rear brake hose hole on the -6 and early -4 are smaller and use a 911 hose and mounting hardware. the 74 uses a vw hose and vw mounting hardware. Both are the same at the body. One of the -6 arms has a bracket on it to support one of the oil hoses. Get the -6's rebuilt and keep it original.

I was just kinda look`n for a quike turn around .In and out of the shop .I will have to be one of the winter projects if i keep it all real ...but thats ok to. it give me something to look forward to this winter and while its on JS i will do the front as well

Late 914 trailing arms have a slot in the brake line bracket to allow the brake system to be separated from the tailing arm without cracking open the lines. Early 914 arms (including 914/6) have a brake line bracket that is completely circular, so in order to remove the trailing arm, you have to crack open the brake system.
They are interchangeable and I'd bet money that even the most thorough concours will not pick up on that subtlety.

Early 4 and 6 are the same:
-Round hole brake line as Mark mentions
-Extra tab welded on to accomodate the -6 flapper box cable.
Late 4 are slightly different:
-Slot line holder as Mark mentions
-No extra tab for -6 stuff
Search is your friend. I've posted pictures of the differences in the past. I have a pair of each in stock and powdercoated, ready for fresh bearings.
