Z Bar Bracket?

I have a 67 f100 that was originally a straight 6 3 speed. I'm swapping a 352 and a t18.

When I went to reinstall the Z bar, it seems like the ball on the bell housing sits about 2 inches too far forward (towards the front of the truck) and doesn't line up with the ball on the frame side bracket. Is there a different bracket that I need for the bell housing?

If so, is that a junkyard/ebay part or can I find it online/lmc/etc. Thanks


******UPDATE:
when I did my engine swap (from 240 to 352) I didn't move the engine perches back. There is a second set of mounting holes that are ~"2 back from where the perches were mounted. I moved the perches and everything was square.

Sounds like maybe the engine needs to be wiggled around on the engine mounts to line it back up.

I don't think there is 2 inches of wiggle room to be had. You would have had to put the engine in with the wrong mounts, and then it wouldn't have mated to the transmission.

Get and post some pictures. Mine is a 4WD but it may be the same mount. If you post some pictures I may get motivated to crawl under mine and take some for you.

Inline six and FE engine frame perches are the same. Mounts differ. Now if the wrong mounts were used, that might explain some of the problem.

On an FE-truck, the engine-side Z-bar bracket bolts to the front face of the engine block. The frame-side bracket has some adjustability but not two inches. Maybe one of the parts ghurus could look up whether there is a difference between a 240/300 bracket and a V8 bracket.

For what it is worth, here are the diagrams from my '69 shop manual.

I don't recall that, mine conforms to the drawings I just posted. The whole assembly is behind the engine.

Look at PN 7A572.. the bracket bolts to the front face of the block and then is formed as an ell and its ball should line up with the ball on the frame-side bracket.

I've got three manual tranny FE-trucks (TKO-500, NP435, and a T18).. all of them are configured the same.

Not having experience with both a six and an FE I didn't know the perches were the same, makes sense, and there are a second set of threaded holes in the frame on my truck. Having said that, it would certainly mess up the position of the transmission if the whole assembly was in the wrong holes.

Also the blocks were drilled for both car and truck positions for the engine mounts, so there is possibly room for multiple errors.

You are probably right, I'm too lazy to go and look! It certainly mounts to something in front of the bell housing and the only thing there is the block.

I'd call my experience intimate knowledge..

On my 4x4, the engine was misaligned (by the PO) and the clutch action cracked the bracket. Rewelded and all is good.

The more recent TKO swap resulted in new plastic pivot *****, felt washers, and packing the Z-bar tube with grease... Did you know that the Z-bar tube has a grease fitting? Look underneath!!!

All Bumpside engine frame mounts are the same with exception of the mid-year '69 addition of the 302 engine and its specific perches to that engine. They are shorter than the I6/FE perches and they push the engine back more towards the firewall.

The second set of holes were factory drilled on mid-year '69 models and later. Models prior to this don't have the additional holes in the crossmember, from the factory.

The Equalizer (Z) Bar is the same 240/300 & 352 for 1967 F100/350.

The outer pivot (located on frame rail) that the bar rides on is the same 1967/72 F100/350 I-6 & V8.

But, there are TWO different inner pivots.

240/300 I-6 inner pivot is a stud (7A535 in pic).

352 V8 inner pivot is affixed to a bracket (7A572 in pic): C6TZ-7A572-M = 1966 F100/250 352 2WD / 1966 F100 352 4WD / 1967 F100/350 352 / 1968/72 F100/350 360/390.

Maybe I'll get un-lazy and go and look for it! Lately all my attention has been to the top of the engine since I just put in a new 445 I built and I've had issues starting with too much pre-load on the lifters (followed the manufacturer's instructions and it left me with hanging valves) and some header fit issues that have kept me from getting the carb set up correctly.
