Yes, the dowels line up and centre the F23 transaxle correctly on the engine. That's why I'm posting all this, to allow others the opportunity to do HF swaps without having to track down and install a Saab F40.
The F23 is the easiest and cheapest transaxle swap for the Fiero. Stock axles, adapters available for the clutch and linkage, cheap low mileage transaxles available in the scrapyards; mine was $94. The HF FWD engine is becoming surprisingly affordable as well; I bought my 2012 Impala LFX engine with 20,000 miles for $800.[This message has been edited by mender (edited 02-26-2016).]

Do you have the half shaft that came on the HFV6? Would be interested in seeing pics of that bolted up and just resting in the diff area to show the angle.

As far as I can tell, the F23 is in the normal location, same as it would be if it was attached to the stock 2.8. No measurements but based on visually comparing it to my other Fiero that is up on the hoist beside the LLT/F23.
If you look back to Dobey's post with the 60 degree and Q4 bellhousings and compare the dowel locations to the axle location with a straight edge across the screen, they look to be very close, enough so that I suspect they are the same.[This message has been edited by mender (edited 02-26-2016).]

No, I bought just the engine.
I've installed the right side halfshaft into the F23 to make sure it clears the HF engine and it does. Do you have any pictures of a stock configuration? If so, maybe I can use that to compare where things are at. What are your concerns?[This message has been edited by mender (edited 02-26-2016).]

My concern is whether the transaxle is rotated slightly. Looking at the pictures, it seems like it would have to be rotated, for the dowels to line up. With the transmission mounted in the cradle with stock mounts, as it would be with the Q4 attached, it seems like the HFV6 might be rotated either forward, or rearward, rather than level. But it's difficult to tell from your current pictures. If this is the case, it should be visible with the HFV6's half shaft and bracket, as the shaft should no longer be parallel with the engine if the diff is in a rotated position from where it should be. Or if you place the engine and trans in a cradle with the stock trans mounts attached, as then any rotation of the engine versus the transaxle should be evident.

I'm not sure a slight rotations is worth worrying about.

Depends on how much it is, which direction, and how the car is driven. If the car is raced and the change in angle helps force oil away from the sump, it could cause starvation and critical failure of the engine. I think it's a factor worth determining and measuring, so that those who wish to go about a swap using this trans can determine for themselves whether it will be worth worrying about.
The fact that the F23 bell housing is smaller than the HFV6 bell pattern is probably more worrying for most people who want to use the swap in a street car, assuming the change in angle of the engine is very small.

As you can see, they are all different. I'd definitely like to see how much hacking up of the Q4 bell housing you had to do, in order to mate it to the HFV6 though. |

Anyone else having trouble seeing the middle pic?
The thumbnails all show up for me, but when I click on the middle one, I get the "broken picture" icon, instead of a pic.
The others work fine.

Weird. I am seeing the broken pic icon too when clicking to show the large size. However, if i copy the URL for the image and paste it in a new tab, it shows fine. And after searching for the image, I see it embedding fine in other web sites. Quite odd.
