I am looking at an IRS this weekend. The salvage yard is unsure what type of thunderbird the IRS came out of. All he knows is that the IRS unit is 2.73 Locking. I and am unsure of the method to verify if the Axles/CV joint are correct. As far as the method for measuring the axle diameter, I have read two different methods 1) Measure the shaft OD under the CV joint boot or 2) Measure the shaft OD anywhere along the shaft between the CV and spindle Boots. What ever method, the diameter should be 1.2". What are your thoughts.
Thanks in advance.
