it's a 90* wrench that is sold. it hooks up to a 3/8" wrench. i preffer my
180* swivel, ratcheting box end wrech. either works great.

 

You can use a wobble extension... crowsfoot.. whatever you prefer. Craftsman sells kindof an "L" shaped wrench that works perfectly, they carry it in most stores & it's only like $10. I didn't see one on Craftsman's site (there're a 1000 wrenches to wade through) but this link has a pic of the wrench I'm talkin about.

13 mm wrench lol...it fits seriously. With A/C you can get it in there between the A/C bracket from what I remember. On my 87 I don't have anything in the way but on my old 92 I was able to do it all stock

I have the 90 degree tool and forgot where I put it since its not needed

 

Pretty sure its a 1/2" closed ended.

 

13mm is slightly larger than 1/2". Either works for that bolt.

Google a "distributor wrench", you'll find 'em in 1/2" (for Fords) and 9/16" (for GMs).

 

I always use a 3/8 drive 6 point 1/2" swivel socket with a 12" extention, and of course a ratchet. LOL.

 

That's what I use, but with a universal joint, don't have swivel sockets.

 

....simple 1/2" or 13mm box end works for me..... rightey tightey, lefty loosey

 

I just bought this one:

i have a similar one but picked it up at Hi/Lo (anyone remember them?) its Lisle brand.

 

wow..i gather you've never done this before. what exactly are you trying to accomplish?

 

I have a short 60 degree offset wrench for that.

 

I just use an end wrench most of the time.I can also get to mine with a standard 1/2 inch socket and 6 inch extension.

 

1/4" drive with an extension, it is an American bolt, 1/2" with a universal/swivel attachment.

 

Thanks for all the replies! As for why a need it I expect it would be obvious, so I can adjust the timing

 

Keep in mind that you will only be able to affect base timing, and you will not alter timing advance.

 

Another 1/2" wrench user here.

 

My longer 1/2" Snap-On end wrench fits in there quite nicely. I've also used stubby wratcheting wrenches too. I have one of the fancy distributor wrenches, which gets used when I think about it.

 

Walk into any parts store and ask for a "Ford distributor wrench" and you'll have one in your hands in seconds. It's a C-shaped thing similar to the S-shaped thing BigTang showed (and which I also have) that allows you to do the wrenching from above the distributor where there's 100% clearance. Using a standard wrench can be a bear depending on the intake and front dress combination on the engine.

 

mine looks like the bottom (aka largest) one in this picture:

Can be used for other purposes too... my father borrowed it to install a new toilet in his camper :/

 

I use a double box in wrench 1/2 on one side 9/16 on the other it is kinda short bit the 1/2 fits great and i can adjust it at the track with know problem.

 

I have a super low profile 1/2" socket with a universal joint on it. I found that using a regular socket with universal didn't fit in there, but I guess it depends on what tools you have. A distributor wrench would be fine too.
