Looking for a measurement - The 1947 - Present Chevrolet & GMC Truck Message Board Network

gringoloco · 11-23-2006, 07:42 PM

Searched and came up empty. Looking for the distance between spring perches on a coil rear at the axle CL. Trying to get all my bases covered before I tear into this Blazer project...

Thanks -Chris

Are you talking about where the trailing arms bolt to the axle? I have an empty axle housing in my back yard that I could measure for you, if that's what you're looking for.

Exactly what I am searching for. Guess I wasn't very clear in calling them 'spring perches', as technically that's not what they are. Somehow that's what my brain spit out as I typed...

Ok, Here's what I got.

I couldn't take an accurate measurement right on the centerline of the axle because of the differential housing.

From center of rear hole on the driver's side to center of rear hole on the passenger's side measures 41 1/4" (See Pic 1)

Since I'm not sure if this is 67-70 1/2 or a 70 1/2-72 axle I measured from the outside of the differential cast housing portion to the OUTSIDE of the brake flange (for lack of a better word) and it measured 21 1/8" on both sides. (See Pic 2 - Red Line)

From the center of the rear hole to the OUTSIDE of the brake flange measured 8.5" on the driver's side & 8 11/16" on the passenger's side. (Pic 2 - Yellow Line)

From the center of the front hole to the OUTSIDE of the brake flange measured 9 11/16" on the driver's side & 9 13/16" on the passenger's side. (Pic 2 - Green Line)

I can't honestly say that my measurements are 100% accurate, but they are +/- 1/8". From what I have seen there is plenty enough play (side to side) in the trailing arms, even with new Poly bushings, to let you be off a little and it not make a difference.

Let me know if you have any questions on my measurements.
