Need help with clutch linkage

[bekeman]

Hello all,

I am new to the forums and am currently trying to finish my build on a 1972 c10 that I added a big block chevy and m21 transmission to. My problem is with the clutch linkage. The truck was originally an automatic so I already put in the clutch pedal from a donor and also have the transmission, bellhousing and clutch fork installed. My issue deals with where to put the rod from the pedal to the crossbar that goes from the frame to the side of the engine. I tried putting it through the hole in the firewall and it hits the headers. Some of the older trucks I saw in the local junkyards had the rod going straight down thriough the floor, which seems like it could work. If I was using a small block, I honestly think I would be able to use the hole in the firewall but the bigger motor takes up too much room. Any ideas? I am totally lost! Any pictures or ideas are very welcome. Thank you
