Hi All

I've recently bought myself a '79 K5 - see thread in the Newbie area here (http://www.blazerforum.com/m_12512/tm.htm).

It's obviously been lifted through suspension, lifting blocks on the body and larger tyres. Can anyone tell me what the stock height and stock tyre size should be for the truck? I can measure the body lift, but would like to determine how much lift is in the suspension. I'd like to know what the stock tyre size should be for a similar reason and to calculate the gearing I'm going to need.

Cheers

Did a bit of searching and found some stuff for you:
Coloradok5.com - Brochures (http://www.coloradok5.com/brochures/)
Click on 1979 and blazer8.jpg is included below showing your stock tire size and the stock ground clearance.

You'll have to figure out what the overall tire diameter of the stock tires was and subtract half of the difference between original tires and new tires from the ground clearance of your truck now. For gear ratio, compare the tire sizes. I do believe that an H78-15B is almost identical in size to a 235/75R15 or 30x9.50R15.
