Summer deadline - 72 Mach 1 Build thread
I removed the brake booster today. It was fiddly and i dont know how i'm going to put everything back together lol. Does anyone know if there is some factory marking to indicate whether booster is original or repro ? also is there a bench test one can do to test it works ? apologies if this has been asked before.

also i was struggling today to remove the steering column, all the bolts are removed on the firewall side, what do i need to disconnect on the engine bay side ?

I'll try and take some pics tomorrow.

The clamp between the rag joint and steering box, that connects the rag joint to the steering box input shaft. One bolt. You can also remove two bolts that hold the rag joint together. You'll also need to remove the firewall plate/clamp from the inside.

I have a "donor" 71 grille, but it's different for 72. Otherwise, I'd cut a bit you need (if still on the donor).

The booster seams be the correct one, tho, looks on picts like a 9 inch. Both my cars have originally an 11. I know you can have both sizes, but I don't know why they are not all of same size. My 73's is refurbished(exterior), my 71 was busted, full of brake fluid. Replaced it with a new one, as sending for repair was too crazy, but have only managed to find a new 9. Kept the old one, in case I ever find a place to let it rebuild or find the parts needed for a rebuild.
If you manage to find a serial, I'm sure @Secluff will tell you where it was made and when!

I know the feeling, don't think about that now! Smile

btw what happened to one of the steering pump tube/base? I detect from the non-round shape the use of "illegalOnMustang" tooling Big Grin

73 modified Grandé 351C. Almost done. 
71 429CJ. In progress

re grill, thanks - I'll send some pics of the bits that are missing to see if this works for your donor pieces

re booster -So, reason i asked, was same as you i guess, if my part was repro, i would hesitate less to just get it replaced with a new one than send it for repair or try to repair it myself. Surprised you gave up on that option Wink

Steering pump removal was a disaster, you just reminded me, i need to get that sorted as well.... 

oh did i forget to mention ? My summer deadline will be coinciding with the 50th anniversary of the car - summer 2022 :=) gives me plenty of time to get a degree in plating, plastic welding, soup making, the works..... maybe even paint spraying....
