I am making the firewall bend to install my cylinder head: http://www.mtfca.com/discus/messages/708324/741991.html?1491329147
I dismounted the lower steering column mount to help with that. Here are the bolts and piece of wood that held it on. The long one went through the wood, the others through the frame rail. Anything wrong with these? Are they the right size? How about the wood? If I should have to replace the wood, what species of tree is used?
Langs sells that block for $2.50...and looks to be made of maple.
They also sell the nut/bolt kit for the steering bracket. Yours look a little bit worn, so I'd get them too. Between their wood block and bolt kit, now you're up to snuff. Get 'em!
These would fix your firewall problems;
Is that fire damage on the wooden block?
You can make your own, use a good hardwood, maple is what Ford did, but good oak will work too.
Be sure your width dimensions are good to make the block fit snug, don't want the steering bracket to wiggle. Your old block is really shot!
oak is a lousy wood to use for the block, Maple or Alder would be MUCH better. Oak is too open-grained and prone to cracking.
I think your bolts are OK, but hard to tell, there's so much rust showing!
I agree with David and so does the ford drawing - HARD MAPLE was the only species used for this part. For that matter every block that I have seen the drawing on was also made from Hard Maple. It is closed grain and very hard - saws great - hard to plane, accepts paint wonderfully - lasts a long time as evidenced by the picture of the nearly century old block above.
