Spring relocation issue questions

[400dartguy]

OK- Im finally gonna do my spring relocation today.  The big question is- in seeing that the major tire fitment problem ultimately becomes the front lower fender lip- could I just move the front spring eye holes back a half to one inch, ultimately lengthening the wheelbase??  What kind of clearance do I have from the rear (8.75 to the stock gas tank).  Im asking because I still have the 7.25 and wont have the 8.75 for a month ($$$).  So does anyone have their 8.75 equipped Dart with a stock tank on jackstands right now so they could take a look-see/measurement right now??
 
Ill start cutting in a couple hours, so any informed help ASAP would be greatly appreciated...

PM A13dart. I think he moved his 8.75 back an inch. 

I moved my Dana back an inch and I was into the tank a couple of inches.

Moved the 8 3/4 back an inch on my Demon, I'm not using a stock tank but it doesn't look to me like it would bem a problem even if I was using the stock tank...

My 68 Dart has the front end up on jack stands so this may or may not change the measurement.

I measure 1-5/8" clearance from the rear end to the gas tank. This is with a 8-3/4" rear end with super stock springs all in the stock location with long rear shackles.

I plan to run hoosier 9x30 radial slicks that measure 29-1/2" tall, so I estimate that I need to move my rear end back 3/4"

Hope this helps some.

Thanks guys- 3/4 it is...   I just wish I had the right axle, wheels and tires so I could enjoy all the work that Im doing this weekend.    Oh well- by the time I get all of that stuff maybe Ill have the mini-tubs done too() 
 So is anyone gonna need a 2.69 geared relocated-perch 7.25 axle??
