wrongpaw, welcome to the Bolt.... now, some time ago I was following a thread that if I remember correctly said that an original style early model header 55-57 might work??? Also most folks that move the steering box use a Toyoto steering box that will mount on the side of the chassis with just a small amount of modifications. Perhaps if you do a search here you can find those posts. I may have them printed out and in the shop somewhere but finding them quickly may be a chore! I also plan to put a small block in my 53panel.
