73+ Tubular A arms on my 69 Suburban - The 1947 - Present Chevrolet & GMC Truck Message Board Network

swissfacade · 12-10-2007, 11:00 AM

Hey guys I just got my hands on a great set of Tubular A arms, The lowers are 1 1/2" tubes and the uppers are 1 1/4".

I wanted to know if these will fit on my 69 Suburban or will I have to change out the front cross member. If the front cross member has to be changed out, What else will I have to change.

The tubulaur '73-up arms will bolt right on. You may have to use the'73-up u-bolts on the lowers since they are bigger. This may require enlarging the hole in the crossmember to 9/16". The only other difference is that the ball joints will be different. Now is a good time to swap to '73-up disc brakes. Good luck.

Hey lolife99 do you know which cross shafts I need to use, the 1969 ones or 73+ crossshafts. Thanks for the information.

You'll use the 73 and newer shafts.

What he's talking about is that the lower arms are held to the crossmember by little u bolts. Some trucks used the smaller u blolts, some the larger ones.

You may need to ream the holes slightly if that's the case. No sweat, about three seconds with a drill bit and a drill will enlarge them as needed.

The upper arms are straight bolt on.

lets see some pics of the 55 belair dash in the burb

I'm not sure what brand they are, I haven't been able to find a name on them or on any of the parts that came with them. They are just stamped GM73. I bought them from a guy on craig list for $300.00 (new just dusty). I haven't installed the 55 belair dash yet, But I do have the original dash cut out. I am going to get all of the parts that I am not using together and post them. I need more space in my garage for new or custom parts for my Burb. I have boxes of new parts just waiting to be put on it, when i get the time! Just working a lot of hours right now.

the bottom ones look like DJM's, but the top ones do not. The blue paint makes me think they are shAIM arms.
