Will a 2.5" rear block/ubolt app for 73-91 work for a 71? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

So I have had rear Rough Country 2" blocks on order through Jc Whitney for over a month, and now they are telling me it will take 60+ days to deliver.

I called Rough Country, and they have plenty in inventory! They are not allocating any to JC Whitney for whatever reason, and the rep was being a d$ck.

So, strike 1 and 2 against JCW and RC.

I called Explorer Pro Comp, and they have a 2.5" block/ubolt kit for 73-91 Blazers, but neither one of us could figure out why it wouldn't work on a 71... Maybe leaf spring thickness?

Any ideas?
