Done some research but just need someone to confirm.
94-98 8.8 mustang with fit a 68 and is slightly wider. Some i'll need extra back spacing on the rim (increase positive offset). Getting a 4 link suspension from heidts, will modify housing to fit. Adjust ebrake cable length. Running all new brake set up. Anything else I am missing?

A 94-98 Mustang 8.8 rear is 58.5". A 99-2004 8.8 rear is 59.875" . If you go with the 95, you will actually be narrower. Stock rear width for '68 is 59.25"

So you could just use wider rim/tires and it should work great!

I believe the OE 59.25 is axle flange to axle flange.

I've also recently found this that talks about the distance for offset.

Ive seen post saying the axle flange to flange is 54" and to add 5 to 6" inches for the drum. Ill just pull my tires and measure all the specs. Why doesnt this forum use stickies? They should be stickies and common fixes, swaps spec, other how to etc. The collective knowledge here is crazy when the one come of the woodworks and post. If you search 8.8 on this forum 90% are explorer posts. The other don't have the answers I need.

I can't recall exactly because it was well over 10 years ago. But I had to go with a Fox 8.8 to get close to the original 1967 width (And I had both in front of me at the time). I believe I was 1/8" off with a Fox 8.8 converted to 5 lug.

An SN95 was too wide.

I had to go re-look it up. Yes, the housings are the same from Fox and SN95, but the axles for SN95's are longer. So I had to get Fox length 5 lug axles for the swap. A fox swap will NOT make you narrower.

79-93 Mustangs - 29 3/16"
94-98 Mustangs - 29 31/32"
99-04 Mustangs - 30 11/16"
Those are the axle lengths. 25/32" longer on each side. I should be able to have 1 inch positive offset on the rim over the stock offset.

Isn’t this for a 9” rear, not an 8.8.

A 95 Mustang rear has disk brakes not drum.

The 59.25" you referred to is the wheel mating measurement of a Fox body 1986-1993 which are factory equipped with drum brakes

1994 & 1995 Mustang v8 cars used the same rear end housing but were equipped with longer (3/4" per side) 5 lug axles, they also have abs rings, this will put your wheel mating surface to approx. 60.75"

I have a 1995 Mustang 8.8 in my 65 fastback using a 4 link cradle from AJE suspension, had to install shorter Fox length axles (59.25) and brake caliper relocation brackets, Google "North Racecars" this company has many options for the 8.8 rear ends and have it figured out, I purchased my axles and caliper brackets from them.
