I'm putting together a big block 4-speed & was wondering what is the means of connection of the clutch fork to bellhousing. I have the pivot piece rivoted to the bellhousing but it just pivots there unlike my small blocks where the fork stays in the bellhousing. I know there is a anti rayttling wire available but that doesn't hold the fork in the bellhousing.or does it. I don't have that yet. Keep in mindI don't have a trans bolted up yet but shouldn't the fork STAY in place while putting the trans in & bolting it up to the bellhousing? I'm confused, shoe

If I remember correctly , there should be a little "hook" or "male end" on the clutch fork itself, this allows you to hook it up to the bell housing and keep it in place. Double check with some of the other members to make sure. I don,t remember the anti-rattling spring ever being used to actually hold the clutch fork in place. JOHN  ------------------

There were 2 different methods Ford used to hold the fork onto the bellhousing fulcrum. I`m not sure when the change over occured, though, mid to late 60`s I imagine.The earlier setup used a wire spring that hooked onto a tab on the fulcrum. The later style used a fulcrum with a rectangular hole in it, & a thin "leaf spring" looking tab rivited to the fork, the spring tab fit into the fulcrum hole. Personally, I prefer the later style, as its a pain getting the wire to stay on the little tab, without stretching it all to he!!------------------

There isn't a hook on the fork or slot on the bellhousing fulcrum. so I must have the early model..I still don't see any means of attachment, Shoe

Shoe, if the fulcrum doesn`t have a rectangular hole in it, then thats the early style. The fork SHOULD have a "wire" across it, if it doesn`t, there should be a small hole on either side, just before the section goes wide (for the throw out bearing)where the "wire" should be.The wire spans the channel, & hooks onto a small tab on the fulcrum itself.If this tab is broken, then you will need a new fulcrum, if you don`t have the wire on your fork, & can`t find one, you may want to try to see if a fulcrum & fork from a 73-76 PU will work, then hit the wrecking yards. A few years ago, while making clutch linkage for my 428 Fairmont, I was able to buy a new, later style fork from Ford, although the fulcrum was obsolete. I found a 302 van in the wreckers, & cut the fulcrum out of the bellhousing from that.Lots of hassle for such a small piece!------------------

My 390 has a "loop" on the bellhousing and a "wire" spring-loaded clip on the fork that slides in the "loop"------------------
