can you drill out your rear?

can you have the axels of a 6 lug rear end for 5 lug? If so is it a big deal or can any machine shop do it? The reason I ask is that my next possible truck is a 69 CST big block with air, t400 tranny and a posi rear end. I already have the 5 lug rims and front spindles from a 72.
thanks

I have had a couple of sets of 6-lug axles redrilled for 5-lug. Any competent machine shop should be able to handle it.

Thanks, how much did you pay for that? I had a 12 bolt rear end out of a 66 chevelle once that had two bolt patterns on it.

It's been a few years, but it was $75.00 for a pair back then.

That worked because your friend's truck was a later model '70, they started making wider rears in the middle o fthe '70 model year. 71 up axles WILL NOT work in a 69 rear end, they are abotu 3/4 inches longer if I remember correctly.
