My 68 Impala Build

[IMPALAMAN1]

depending on bag of choice you do need to trim the pocket.

from experience.
firestone 2500 highly suggest trimming the inner roll or not using these bags at all. I went through a few of them. they always look like they clear... but dont.

slam speciaties re62 trim the inner roll and inner part of the pocket.
im currently running thise in hte front... and love them but it takes me 125psi to lift the front with a 327.

current plans are to swap them out for the re72.. but you do need to notch qute a bit if you want the car to sit low.

the other option is to make a tall upper cup and get the bag out of the pocket..... sacrificing how it will lay.



something to think about on the rear end. im also running the re72 bags in the back on custom control arms.... the location of the 7" bag to not rub in the front of the frame runs into problems on hte rearend itself. the bag comes into contact with the lower control arm bracket on the rear end. i have trimmed mine back to the housing and have not had any adverse effects....
