Best way to reinforce firewall?

[GTFalcon 351]

Just had a look at my mates 5 speed EA and it appears that there is a crack going 3/4 of the way around the area of the firewall where the clutch cable comes through, i hear this is quite a common problem and am wondering what the best method of fixing this is,

i have been thinking about pop riveting a 3mm thick plate over the area from the inside

pop riveting the plate might work, however it will be super strong if you can weld the crack up then weld the plate in instead...

I grinded off the sleve that come through into the engine bay and riverted a 3mm stainless plate on and have had no problem thus far.

I welded the crack up after it appeared, and it hasn't returned yet- even with the monster clutch I'm running these days.

I heard that there is a Ford part to repair the firewall when this problem occurs. Fiction?

its basically a plate that you weld on the outside (engine bay side) of the firewall.....

i need a new clutch soon, what would you recomend to hold about 200-250rwkw? my pressure plate is buggered atm, and as soon as it gets to about 3500 it will slip.

Xtreme make a few that would suit that sort of power. I think EASPRINT has a line on some good clutches too, and it sounds like one of the guys on this forum works for a clutch place. Someone on here can probably hook you up I reckon.

I'm running a tricked up Xtreme and its been awesome so far.
