Stickshift guys, dshaft and rear for 69 Torino

rustang · 11-30-2018, 03:49 PM

I just got this old girl on the road this year, and already had my first rearend blow up lol. It was a stock 1971 torino housing and 28 spine axles. The one axle twisted the splines but I think it was the cheap aftermarket diff that scattered first and took the axle shaft with it. (Additionally the 9" housing spring pads were all bent and welds broken...but I think the rear had been like that from before...which explained why the pinion angle was funky!).

Regardless I don't want to relive that any more. Car is a full weight 1969 torino fastback. It's a 351C 4V/toploader, should eventually be a low 12 car and around 400-ish hp. The plan for next season is to go with a shortened truck housing, N case, Detroit locker, 31 spline axles, Daytona support. One thing I'm wondering about is the driveshaft. Will 1330's be reliable with this combination or should I go with 1350's? 1330 seems to be a lot more common. And if I go to 1350 who makes an output yoke that is 1350/toploader? Will a C6 yoke work?

Well, my car weighs a lot less but I have a stick car and leave at 8400 with 1310 ujoints. When I want to go fast I leave at over 10,000, haven't broken a ujoint ever. In the case of Stock & SS, you will find a lot of lightweight rotating parts just to squeeze out the last morsels of performance. On the other hand, if you're not looking for every last bit of performance, you're not going to go wrong with the 1350's.

1350, with a real yoke, no more concerns.

Make sure you have Steel caps and solid spanners on your N-Case.

I've got a pair of 28 spline axles ready to go if you're wanting to fix the stock rear.
Quick Performance sells yokes. If you want to replace everything I'd go 1350 joints. No matter what size joints use quality joints without grease fittings. I've run 1330 joints without failure. That said when I upgraded I went 1350 with a steel yoke on the rear and a Mark Williams chromoly yoke on the frt. I bought my driveshaft from Strange.
