Measure for pushrod length and you'll need to retune the car.
Even if another person has your exact setup, that doesn't mean the prods will be the same. different motors have different clearances.
If I had to take a guess, I would put 7.425s as per my experiences.

 

Yea im thinking 7.425 and if that is to long I can put the stock one back in till I get another set or get adj ones but that seems like one more thing to fail.

 

Adjustable ones are for measuring for proper length only. Once you get them adjusted to where they fit properly, you take them out, measure them for over all length, and order the proper length push rods.
