my new /old 72

[70CHEVYBB]

I picked up my 72 lwb on sunday. I found it local for 800.00. I must say it is rough. I bought it for a winter truck and a doner truck. I will not be getting my 70 done in time so I bought the 72. It has power disc brakes,good bumpers,4 core radiator and a good bench seat that will all go to the 70. I am interested in swaping the rear axles also. I have read that the 72's axles are 1/32 longer that the 70's will they still fit in the 70's housing?
