Wow, no one?

 

Most of the people that have a MII suspension on here get shamed away from this forum pretty quickly 😝

 

About 1 5/8” on mine

 

Heidts Pro-G IFS (not an MII). I don’t know of this will help you or not Wicked.. Considerable difference from Angry’s.
From the bottom of the frame rail to center of the rack: 4-3/8s.

 

Geez. No wonder you can drop your engine so much further than me.

 

Mine is a Mustangs to Fear front end. I stuck a flat 1/8” piece of aluminum on top of the rack to take a picture. I took a top and bottom of frame rail measurements. These are rough measurements.
The rack is a 15:1 Mustang rack. Sorry the pictures aren’t so good because the car is off the lift for a couple other projects.
I should have it back on in a couple days.

 

Thanks guys. The difference is interesting. I am assuming everying is using a 2" drop spindle correct? This is currently somewhere around 2":

I am aware that everyone is running the MII control arms other than me(you can see the unfinished/unused MII LCA holes below my rack bellows) but regardless of the LCA used, the spindle itself(and thereby) the steering arm should end up in the same location. I was just surprised when there seemed to be so much difference when I follow a parallel angle to the LCA for the tie rod. It does make sense though....since I am using a stock-base LCA the mounting point is so much higher. This weekend I will have to run some string lines to measure potential bump-steer locations....but my suspicion is that I will need to bring the rack up to about 1.25" and run a bump-steer kit to keep everything in line. The only bad thing about this particular MII spindle is that unlike the Wilwood version the steering arms is not bolt-on....otherwise it would be simple enough to fab a new lower arm. What is really interesting is that the stock spindle arm height looks like it would be perfect for this....of course the stock arm is way too far inboard and too long otherwise, but it is interesting.

 

I bought the Wilwood 2” drop spindles. I don’t have them installed yet.
My frame setup came with a set of 2” drop spindles, but I elected to buy the new Wilwoods’ because they are a better units. By bolting on the tie rod arms, you have a lot more flexibility in the bump steer department.

 

You should look at the CPP drop spindles....nice design because they get rid of spindle pins entirely and go with a C7 Corvette sealed bearing hub and Corvette brakes...also you can tune track width from Mustang II default width to 1/2" less per side with the included spacers(whether you use them or not):

If looking for a good spindle...I honestly haven't seen a better design for the MII....being modular counts for a lot. The only downside is that it costs more to replace the hub than it does to replace bearings. You can of course replace just the bearing on the hub, but you would need a press. However...the steering arms aren't bolt on like the Wilwood spindles(my one gripe). I opted to deal with that though since I will likely end up with some type of bump-steer kit to get the tie rod angle I need like this old pic I found:

I actually have no idea what suspension they are using here. Its some type of K-frame SLA setup using what looks to be a MII spindle.....but I will likely end up with a similar rod-end setup. Not ideal, but you can't have everything when building a frankenstein front-end.

Mine is a basic heidts mii kit. The tie rod ends are parallel to the ground at ride height as are the lca’s. I am using the heidts 2” drop spindles.

Yeah...they would need to be to have acceptable bump-steer. The big difference is the LCA height difference between the stock LCA and the MII LCA. Your steering rack tie rods being parallel would end up above the LCA....my steering rack tie rods being parallel would end up somewhere below the LCA. Its this trickiness that is throwing me off, which is why the height of the rack tells me more. Although from what I can see so far, that number seems to vary quite a bit.

I have a Rod and Custom MII on mine with a power fox body rack. 2" drop spindles. My measurement looks pretty much the same as @Anangryford . Here are a few pics:

 

A very useful picture here. It gives me the MII LCA bolt hole reference measurement as well. I can imagine the tie rod will run just below the stock-type LCA if the rack is mounted at the same height:
