Got the cab and bed in the shop and started to work on it and test fit the 99 dash, doesn't fit too bad, but will have to do a little trimming and fine tuning but shouldn't be a problem.
Also started shaving the drip rails, after seeing it done to a crew cab I thought it looked good and also gets rid of a catch all and common rust area.
I hate when work gets in the way of personal projects, any ways I removed the firewall and front half of the floor pan and am now in the process of figuring out how best to install the 1999 stuff, I did test fit the floor pan and it fits pretty nicely but there will have to be a little sheet metal work done for it too look right so I am probably going to by a sheet of 1/16th steel for pieces that will need fabricated and filled in. I will try and get up some pictures soon, I did moc-up the dash and seat with the 99 floor pan and sat in it and just for a rough set up it felt bad @$$.
