What kind of Koni is this?

[mikepellegrini]

The part number is 951 343 031 02. The car (my 86 951) came with the M474 option.

I was thinking of putting in new inserts (because 86 Koni's are supposed to have removable inserts) but this doesn't look like it's removable - at least not like the early NA struts that I've rebuilt.

I put the number into Pelican and their parts finder came up with 951 343 031 06 OEM - the late, non-rebuildable Koni's (said mine had been superceded by the new part).

I can't find the number of my strut in the PET Katalog - just the later parts.

Here's the pic of the top of the strut. I guess the top could be threaded inside or something?

Have I got late struts or early struts on my car?

That PN doesn't show up in PET anywhere between '85-'91.

If yours is an '86 951 with 474 option, then it should have 951 343 031 11 and 951 343 032 11 struts.

From the picture you posted, it looks like they are "rebuildable" struts which you can send back to Koni or some other shop and have them fixed up or even revalved.

I would check on Paragon's website, as they seem to have the most complete Koni selection I have found.

Hope it helps,

The reason I believe they're original model 86 Koni's is precisely because the number doesn't appear in the updated PET Katalog - they were superceded by the parts you mentioned.

Koni sport struts through model year 86 are supposed to be rebuildable.

It's just the Sachs struts I've rebuilt (put new inserts in) looked different - there was a cap threaded on the outside that screwed off; you put the new insert in, screw the cap back on, then you're ready to go.

This cap, if it does screw off, I could probably take off with a pipe wrench.

944 Online sells Koni inserts for these struts - http://www.944online.com/cgi-bin/ASI_Store.cgi?Product+skukey_20052383+944turbo+Sus pension-944turbo
which are about half the price of new complete assemblies.

I just wanna make sure mine are rebuildable before I oder new inserts.

That looks exactly like the new inserts from Paragon I have here in my office. According to them the 86 Turbo requires these. They are not like the change out inserts but they sell these sport option replacements. They also have a nice pictorial of how to cut up your old struts and use these. http://www.paragon-products.com/product_p/koni-8641-1414s-conversion.htm
