well i called dennys and they said there would be no issues. they nomally shoot for ~1", so my 1 1/8" isnt too much. he said that if it were 1 5/8" he would worry a little. i never really asked what the issue would be if it were a little shorter. im not sure if it would be a vibration that would ruin the bearings on the output shaft, or if the reduced spline engagement would result in a failure from twisting.
i also started on the fender extensions today. although the first pic is the opposite side, both were about the same. even though it appears the hood could have been shifted back to get a good gap, the angle at the front of the fenders were wrong leading to a crooked gap if the hood was back and the extension was flush on the fender. i welded up the gap along the top and down the side and filed it down to fit. i still need to work the area towards the center of the hood since its about .030 too tight. so far i have about 4 hours in this since it took a lot of twisting and hammering to get it to fit pretty good before working the gap.
heres the first pic. in order to get .175 across the entire gap, it had to be pulled out. i had thought about spliting the extension and tweaking only the hood side out, but decided this would be cleaner.
heres the second pic. it snugs up a little more, but im holding it in place with one hand and snapping the pic with the other.
and heres the other project ive been working on. so far i have about 4 hours in this as well. way too much time for how little work it appears, but getting it all set up and repositioning takes a lot of time. plus i can only take about .050 in depth and side bite at a time. it will get recessed in the trans tunnel and it will be held in place with some screws that i havent drilled for yet. its obviously not necessary, but i like playing with the mill. each project shows me how much money i need to invest in good tooling.
