Length of travel for hatch "roller"
 

Trying to design a simple mount for the Lift Arm under the Hatch. Can anyone measure what the length of travel is on a center mount factory roller setup? I need to determine how long to make the mount and I do not have anything available at the moment to measure. Easiest would be to measure the witness marks on the channel under the hatch where the wheel goes back and forth.

Need minimum dimension in picture below, hatch closed / hatch extended. .

I assume you're all busy measuring?.......

Can't be much more that 14-16" ?

Hmmm, I bet there is an engineer on the forum that could help.....

Really anyone that can operate a tape measure is capable. Oh yeah 1990-2000 non-step gun, preferably a TRS setup, although I am sure they are all the same?

Dave, still got my old hatch with the channel on it? Can you measure the witness marks?

All the same, I'm gonna say 14" roughly. Don't have access to a boati can measure but I've had my hands on enough that I'm going with 14

Frick- sent you a pm - OAL length of the hatch bracket is 10.75"

Ill see if I can help you with that question this weekend.

Thanks guys, trying to get ahead of a potential roadblock.

I have to make this bracket and swivel mount that attaches to the tip of the arm. Will post pics when complete. Hoff came up with roughly a 9" slot length (thanks), any thing different before I start to make chips?

i still have the old slide and the travel is 6 and 1/4" (actual slot length 6 and 5/8th) and both side of the hatch where they will mount are flat and linear from front to back and about thre inches wide so they and bolt anywhere (pretty much exactly like the 39's) Also the original slot length worked for the flat hatch as well as the 575 hatch so nine inches should be plenty of throw. If you use the same basic dimension (arm length and such) of the one mounted in the center all should work good
