Since the tbird irs is so popular and I have both the 7.5 and 8.8 sitting here, I'm sure a lot of folks would appreciate a side by side comparison. I didn't check to see if this is a 28 spline or 31 spline 8.8 diff. Both iron and both open.

The 7.5 is narrower at the inner cv cups, which are larger on this 8.8.
The 8.8 is 90 lbs.
The 7.5 is 80 lbs.
The 8.8 needs an extra 1/2 inch of clearance above the diff and hangs below the axle a lot more, where some run their exhaust so ground clearance is less.
The pinion flanges were the same.

If anyone wants a specific measurement, now would be a good time to ask.

Shocks/dampeners/coilovers

I compressed the springs the first inch (which will have the least rate from the most active coils and other reasons) for an idea of the rates.

The original spit springs indicated a 200 lb rate. From ride height, I'm guessing 225-250/inch.
The blue coilovers indicated 250 lb rate. I was going to use two per rear corner but I think I will use one on each corner instead. Then I won't need to cut the tub corner at the rear and I will have more clearance at the front uca.

Picked up some more steel for the frame yesterday. Next step is to fit the cut bits up into the tub picking up the attachment points, mirror the other rail, then bring it to the chassis. Cross bar cut extra long since I don't know how long it will need to be until I have arms and fit the coilovers.

Cut myself prepping a pork shoulder so it was for a good cause, but it has slowed my roll a few days.
No problems at all with the build.

Thanks, not too bad and the pork turned out great this time. I've been working my way through a 30 lb case I bought last summer, trying different methods slow roasting, pressure cooking, and combinations of the two. Self-less perfectionism for perfect pulled pork? :shock: You're going to make me blush! :cheers:
