Default 65 vs 66 Frame Differences

I have a 1966 327/300 Conv with a rotten frame. I found a good looking frame from fogaley, but it is a 65. I have no welding equipment and very little welding experience. I don't think there would be major changes, but I'm thinking about brake/fuel line clips, park brake locations, etc... Any things I should be planning for if/when I get this frame home?

Offhand, I can't think of anything different between a 65 convertible frame and a 66 convertible frame other than threaded holes for the gear shifter on the transmission crossmember. That's mounted on the crossmember on a 66, while it's on the transmission tail housing on a 65. Fuel, brake, parking brake lines all go in the same places AFAIK.

Doesn't the '66 frame have the access gap in the crossmember so the front to rear brake line can go through it and NOT have to go on top of the frame like the 63-65's?

If that is the case, simply make the modification, since you have the entire frame bare at that point.

Jeff: Believe you are correct on that. Ran into that little issue on my '65 when replacing the line with the body on. Mike

Early 65 frames did not have the recess in the front crossmember for clearance of the big block crankshaft damper.

Please take the time to actually physically look over the used replacement frame. You need to look at both the top side and bottom side and all edges because when buying used anything especially a structural frame without knowing its actual history you are putting yourself at risk.

I purchased a rust free used frame out of Florida that was out of a low mileage C2. The seller provided lots of photos and also allowed me to discuss the frame quality with his head fabricator who told me the frame was as best he has seen in a long time. So off it went to the west coast without my inspection and it was crap. Unsafe, the front spring pockets were fractured. No recourse.



Please check all welds and post and photos that indicate potential questions.

You might consider taking a frame spec sheet with you and cross measure to make sure it is straight. Eyeballing it isn't good enough.
