Oh yes! In my case it found me, only tho....i havent found the money for it! Its really sad too cause i need it in my life!!

Are you thinking about getting it? Because cool factor shoots straight up to 100!

 

[doggiedoc]

Oh snap! I need to find a bellhousing now.

Will an 03-04 Cobra work? Or another?

03-04 cobra bell housing will work or you can get a quick time bell. The quick time bell is a lot more hassle because you have to take measurements and make sure the trans input shaft is centered on the crankshaft. Sometimes you have to use offset dowels to make the bell align correctly. @white95 just went through this. It’s a hassle.

Yes. It’s a pain in Williams neck to use the QuickTime bell housing but it is quite the unit. You’d be hard pressed to destroy it.

*note*

That driveshaft comes with 1350 u-joints and the rear flange uses the large bolt pattern. Assuming you still have a solid rear axle, order this rear flange to retain the 1350 u-joint but work with your 3.5” companion flange:

Thanks! I found an 03 Cobra bellhousing on eBay. I may pull the trigger on it if I don’t find one cheaper soon.

Now I just need to commit on wide ratio or close. I’ve got 3.73 gears so I might go with the wide. But I really like the super low 6th for highway in the close. I wouldn’t mind hearing y’all’s opinions.

 

[white95]

I have a wide ratio box with 6th gear being .50! I bet it’s gonna be nice on the freeway.

 

[doggiedoc]

I thought the wide ratio had a 0.63 for sixth. 2.66 first.

Uh oh, did I read that wrong? Let me see...

Yup, sure did.

So, .63 sixth gear @ 2550 rpms (4.10 gears, 25.53” tire) should turn 75 mph for me. Perfect.

hey i just saw a t56 for sale on FB marketplace for $1900. Just saying.

 

[doggiedoc]

Ya. But I’d still send it up to Tick Performance to get the upgrades.

Ordered the driveshaft and Sonnax flange just now. Thanks for the heads-up!

 

[doggiedoc]

Thank you for your order,

Please allow approximately 10 weeks for this to be completed.

Craptastic! 10 weeks for the driveshaft to come in. Jeeeez!

I tell you shipping has been ridiculously slow
That is a bummer

I just got off the phone with Tick Performance, where I ordered the customized T56 Magnum - they only expect 2-3 weeks to be ready. Just placed the order this morning. So maybe .....
