79 Burb to 72 Blazer front axel swap?

[gstuck3]

Will the front axel from a 1/2 ton 79 Suburban fit a 72 Blazer easily?

Should I just have the original axel rebuilt? How much would this cost?

I am looking to buy the Blazer and the guy said the front carrier is cracked and it needs head work. I have a 79 Burb for a donor vehicle if needed. The Burb is my daily driver right now but plan on getting rid of it anyways and am trying to find any reason I can to get the Blazer. If the axel can swap I should be good to go cause I have a good engine to put in it. Also, do they make a/c compressor brackets for now accessory hole heads? And how do you do that np205/203 doubler thing? Thanks.

Yes! It is a direct bolt in. Just make sure the axle ratios are the same.

I have the front axle from a '77 K20 in my '71 Burb.

Yes, fits like a glove. I had one out of a 80's truck under mine for a while.

The Burb has 3.73's and I'm sure the Blazer has the same. What could cause a carrier to crack?
