Default Dewitts SP461 install

Hi all, has anyone installed the Dewitts (SP461) (90'-96') upgraded cooling fans? Specifically on an LT1/LT4 application (92'-96'). I have an LT4. Notes for the cooling fan say the accumulator must be relocated. Where/how did you guys relocate it? Photos would be much appreciated if you have them but not required. Also how is the fitment if you have a camber brace (Van Steel)? Looking to pair this with my dual core radiator. Thanks!

i moved the accumulator towards the center about 3" inches, found an inboard screw to bolt onto and drilled for another clip to attach the other screw. then i took the a/c hoses and shortened the one side 3" and lengthened the other side 3" . i also relocated my coil assy to the center of the crossover support.

This is gold! Thank you! Hopefully I can get away with not moving the coil and or having to get rid of my camber brace but if it comes to that Ill just get rid of the camber brace. So really all you did was accumulator wise was cut the aluminum part of the line on one side of the accumulator and add it to the line on the opposite side?

first, i moved the coil and icp off the passenger head to get it away from the heat. second, i took the hoses to an a/c shop and had them make up new hoses that were 3" shorter on the short hose and 3" longer on the longer hose. besides, they were 23 years old.

I hope its not asking too much but do you have shots of the engine bay? from both sides? Just want to get an idea as to how everything would be routed and look.

I have to get my a/c serviced anyways because I bumped the line going to the evap canister the other day and it started hissing louldly. didnt hit it too hard but just must have been old. I dont mess with a/c components so I hope to just have a shop knock the repair and also install of the new fans at the same time. Just finished rebuilding this motor and doing somewhat of a restoration on this car. I love it but kinda burned out so yes it may not be cheap but Id rather have a shop get it done quickly so I can continue to drive it.
