Well I guess you would be the first here to do a v8 swap in a first gen,and post pics of the rear ends.

I know myself,would like to see it.
Keep pics of your progress

I didnt know I was correcting your spelling

You can use imageshack.us

For the cage,check out chassisengerneering (spelling might be wrong)
They are in FL.Their prices are really good,You still need to notch out the pipes at the joints.

If you are narrowing a rear end.
WHY stay with the 8?
9s have a HUGE range in gear selections,and get the 31?Spline axels,from Mosey or who ever you can find,they come dime a dozen for 9s.

Since you are narrowing down a rear.
You DONT need to "tub" it out..
Heres proof



stock wheel wells/narrowed 9 look at the tires


For the fuel cell,You dont have to completely cut out the spare tire well.
You can cut down into that for the fuel cell.I dont think you are going to run anything bigger than a 10,but if you plan on doing that.You can just add a sump onto the stock tank.

We use inline fuel pumps on the first gens,You can get the 300. aeromotive or just go with a inline walbro 255,for like $115.

Im not sure who this post is directed to.Im not good with riddles.. so I guess I loose?

I read your post 5 times,and have no dam idea where you are getting at.

How "narrowed" the rear end should be,places in a BIG part of wheel width and offset,and if you are using stock wells or if you are going tubbed.

But since you rake some bread in,I think John Force is still doing side work.
