Blazer or Burb tank

[BadCompany]

I am getting ready to attempt a rear tank install on my '87 swb fleetside, and was wandering how far the tank hangs down under the bed after the install? I have read a ton of peoples builds, and it looks to be a pretty straightforward install but cant seem to find any finished pics with the bed installed. I dont really want to do the swap if its going to be really noticeable with the bed back on, so if anybody has any good pics from the back and sides after the install with the bed on please share them. Also would like to know if the sending unit in my 16 gal. saddle tank would work in the burb tank, or would i have to buy a new one? Info and pics are much appreciated. Thanks
