im looking at my 72 gs 350 wondering what combo gives you access to adjust the distributor. Thanks
Personally, I have an army of Snap On, Mac, Craftsman + KD distributor wrenches. It's difficult to get at that bolt easily unless you have different length extensions, a swivel or swivel socket. If I could have only 1 60's 70's distributor wrench, it would be this one. It's like my very fiirst wrench.
The beauty of this thing, is that it comes apart in the middle, so you can turn it any direction you want, or put a ratchet on it. Because each end is different, it does mostly everything except metric. I carry one in some of my cars. Early KD 104's were made in USA. Later are not as good but still ok. There were a lot of cheap imported variants, too. This will do BOPC, Mopar, Ford, whatever. You can maybe find a clone on ebay or Amazon for like 10.00 new.
Here's a really cheap one that will work fine. The tolerances on the actual 1/2 or 9/16 size won't be perfect, and the center joint may wobble a bit. But it should get the job done, and it's cheap!
I use a 3/8" ratchet, an 11" extension and a crows foot wrench . Works perfectly
AutoZone sells them. Around ten bucks I think.
I have a distributor wrench in my toolbox for a Cadillac HT 4100 engine. Used it once about 25 years ago. Still there....
Thanks gents. Very helpful. My car has 3:42 non Posi....I was impressed that it would do a brake stand and a 2nd gear chirp when it shifted under hard acceleration. I need to open quadrajet up this winter and see what primary circuit is .....as the secondary circuit was super lean.
The best wrench I have found is the old Snap-On S9838 works great on Buick 350/455
They come up on Ebay from time to time.
A link for reference:
3/8" drive crow's feet on a 6" or longer extension should work fine.
That's what I have. Works great.
