I can't thank you all enough for the info and pics. Those old plans look spot on even down to the tie-bar mount incorporating the steering idler mount. There's more pics of the frame here -

The history of the car is really overwhelming and I've found myself just standing there looking at the frame in awe of it's past.
I'd like to eventually restore it back to an earlier guise but I know that the budget isn't there right now for a blown hemi, so it may get another mopar motor for now but without modifying the frame so that it can be fully restored in the future.
Thankfully I have Sid and the SNS Racing team as mentors and hands-on supprt, as well as the wealth of knowledge from members on here, so I'm really looking forward to being a part of preserving the dragster.
