Re: my 79 cobra project
7.5 may surprise you as to the abuse it can take.

Re: my 79 cobra project
Mustang 8.8s are so common and cheap to buy, I wouldn`t waste a dime on a 7.5" rearend.
The stock 79 4 speed is a weak, very poorly geared 3 speed with an overdriven 4th, again, I wouldn`t waste any time on it. Assuming this is to be a Stocker project, it is much better to buy decent parts from the begining. When I started racing my 85 Mustang, I was running stock T5 transmissions for the first year. By the end of that year, I had 2 broken T5s, and a box of damaged parts.

Re: my 79 cobra project
I was saying that about the 7.5 if you were just trying to get started racing with what you already have to work with. As stated, you definitely want the 8.8 if you are planning on making serious power. I've seen 7.5's take abuse but the 8.8 is the best setup ultimately.

Re: my 79 cobra project
I blew up three 7.5's in my '83 then put in a 9".....that was in '88...haven't broke anything since.
9" isn't required with a 302 2bbl auto, but if your ever going to step it up in the future it's required and the price is a wash or cheaper for a 9" imho. Personally I'll always take a robust, removable carrier type rear, over a c-clip/tiny/weak/integral carrier type. Maybe I'm too old school? |

Re: my 79 cobra project
The best info I can share, talk to Mark Yacavone about a converter if you go auto. I was going to start with a 7.5 as well. You can get better axles, and they are 40lbs less than a 8.8. They will hold up to a 2bbl 302 and automatic. It depends on what you budget is and what you are looking to do. I bought a 79, and was going to build it as an 82 HO, but that's done with now. I tried to do it budget, but my 'budget' and a stocker 'budget' are vastly different...
