I have a jag rear with 2:88's will 3:42's fit in the case?
 
I want to go with a different ratio. I'm going to sell my 4 speed (currently apart) and install a 5 speed so I want at least 3:42's

The CWI site lists 2.88 - 5.11, but doesn't say whether they will all fit on the same carrier.

2.88 has a unique carrier.
3.07 to 3.73 and (4.10) take the low case.
3.91 and bigger take the high case.

But a 2.88 will work with a five speed until you can find a different carrier.
Note: the total first gear multiplication on a stock 427 AC Shelby Cobra is 3.54 (stock diff ratio) * 2.32 (1st gear, close ratio toploader) = 5.86
Now your set up would be 2.88 * 2.87 = 8.27
as you can see 8.27 is a lot more total gear reduction than 5.86 which is about the lower limit and not burn up clutches.

Hope this helps

Actually, with an "original cobra", the gear multiplication would be 2.32 x 3.54 which equals 8.21, very similar to the TKO600 1st gear 2.87 with 2.88 rears.

With this combo, definitely get the 0.82 fifth.

Another option would be to use a wide ratio toploader, 2.78 first, and with fourth 1:1, with 2.88 rears, you really don't need a 5th gear.:)

Thanks guys. Damn! Anyone want to buy a rear?

I ran a 2:88 rear with a Richmond Gear 5 speed (with the final drive being 1:1, not an OD fifth) and the car had an extremely usable power band.

Anthony,

Thank you for catching my mistake.
