I did this last May, gonna do the rear's next month

OK, I bought the Coil-over part list from Mo's website, www.ndneyes.com

Since the 1985 shock towers are wimpy and narrow, I cut them as seen in the pic below.

Then I machined some 1/4" thick 1018 CRS to match the same angles as the stock towers and ol'RJ welded them up.

The last pic is just the mock up of the new QA1 in the new tower.

Once the wheel well area was cleaned it was repainted,

Just an FYI, vette2vette.com and tabercorvetteparts.com had 1990-1996 front shock towers you can buy and weld onto your 85-89 (not sure where the thin towers end and the wider towers begin) to replace the factory towers.

The early years shock towers use .125" thick steel and the later years use .160" thick steel. I used .250" thick on the sides and .375" on the top due to the larger span

I would say that it would take @ 4 hours to cut off both towers,
1. IF you had a decent air compressor using a cutoff wheel
2. and a spot weld drill bit,,,
3. and if you removed the lower ball joint nut and swing the a-arm up out of the way.
4. Then you need access to a 220volt welder of your choice,

Very nice. How does the ride compare to the monoleaf?

Any track time on this setup yet?

(And did you hafta use a 2x4 to hold the hood up, or did you upgrade to the strut?)

I've heard the front spring can be a pain. Whats the process there? I may be doing this, front and back, soon.

Thanks

I bought a strut from vette2vette for $30 if I recall.

No track times yet.

The front rides great, very responsive but no roll when I dart back and forth.... Overall I cant say definitively until I do the rears in the next month or so.

If you have a newer Vette i.e. 88 or 89 (?) and newer you just bolt the shocks on in the front, add the HEIM link and you are done.

On the rear there is some finessing,, go to www.ndneyes.com and you can get part numbers etc .
