Yes, you might be able to get away with the block of wood like Jeff (Mr.Drivability) did his. I dont personally like doing that on the pan, but to each their own right? You only need enough room to slip that small tube in there so just unbolt the mounts and start raising the engine up a little at a time until you get the space you need to slide that brake line in there. It always starts as, I need to take care of this and it just starts snow balling...lol and you keep doing more. Thats why I am now doing a full restoration...lol Oh, and that pic of that frame isnt mine. I found that was a good example of where the line has to run through. This pic of the subframe is mine and here is where I am at with my restoration, waiting on the body shop. Engine is currently getting built and rear end and front subfram/suspension is completed. Good luck with replacing that brake line!
