Re: frame rail question

I wouldn't think there is any difference in the sub frame rails between 67, 68, and even 69. I know the suspension arms were slightly different between the years, but that is all I can think of at the moment. There are Big Block / Small block differences. But I have been wrong before soo.....

He's asking about rear frame rails, not the subframe. The only differences between a big block and small block subframe are the engine stands and the trans cross member.
I don't believe there are any difference between the rear frame rails, but let someone else answer. Have you looked up new replacements? What do those say?

Re: frame rail question

all suppliers I've seen have rails for a 67 and rails for 68/69. The supplier near me has rails for 68/69 already notched for mini tubs, Im curious if I could use them on my 67 and save a little fab time and welding supplies

Re: frame rail question

I guess I should've read REAR frame rail! My bad. Looking at a couple of different website's the 67 and 68/69 have different part #s. I couldn't see any noticeable difference between the two, but obviously there is a difference other than the $50 each price tag difference.

Re: frame rail question

1967 frame rail length is not as long as the 1968-1969

1967 bump stops bolt to the bottom of the frame rail.
1968 bump stops bolt up somewhere, I am not sure.
1969 bump stops bolt to the side of the frame rail.

I think the 1967 does not have the emergency brake cable bracket like the 1969.

Re: frame rail question

Since the use the same floor pans, Same leaf springs, that the added length is behind the shackle mount - Do you agree that it would be possible, with minimal mods, to shorten the 68 rail to fit my 67?

To save 50 bucks it might be worth it.

The back of the frame rail has some flanges that are bent 90 degrees. You will have to cut the frame rail and weld back on the flanges.

You will have to drill the frame rail where the bottom bump stop goes and weld two captive nuts. You should fill in the side bump stop captive nuts.

The emergency brake cable bracket is spot welded to the frame rail. They are easy to remove.

You could buy an Art Morrison rear suspension. The different models of suspension comes with frame rails.

Re: frame rail question

"Wish I could afford the Art morrison setup - A bit out of my price range"

That is why the was put at the end of the sentence.
I got it stuck in my head the independent rear suspension is $8000.00.

I was mowing the grass in the front and my neighbor stopped her car to talk to me. She asked me why I mow my own grass and why don't I hire somebody to do it for me. I told her that if you add up all money it costs for someone else to mow it, the money totals to a sizable amount at the end of the year. She told me "Oh well, Maybe next year you can afford it". I am happy she moved away.

So what did you decide? You going to keep the 50.00 in your pocket and cut the cheaper one?

Re: frame rail question

I'm planning on getting the 68/69 rails and cutting them, I can save a few bucks or get the set pre-notched for mini tubs at the same price as the 67 rails- And save on fab-time/cutting/welding/etc.. Either way I come out ahead.

The only thing left now is to start , My boss likes to say " all we have left to do is everything" Seems to fit this project
