they fit. its just that the pasanger side looks too close to the firewall about 1/4 '' its this good enough.
If there is an airgap and the headers are not ratty-tat-tattin' on the firewall, you should be golden. I don't think I'd worry about it if I were you.

I had the same problem on my 1992 pickup.I removed the heat shield and everything is fine.
find out whats behind it in that location... if you've got the space behind it, a BFH should resolve any concerns you have.
i had to remove the passenger side heat shield . i cut it a little and was still too close so i didnt put it back.
it should be ok i have some heatshield stuff that i put under my carpet i while back.
i used 1'' set back mounts so dont know if everyone is seen this results ,
on my 97 the heat shield is like 1/2-3/4" away and i have no problems installing them using dirty dingo mounts other then i used header studs and that took a little grinding on the a-arm to slide them up in there.
