73/74 Roadrunner questions

First question is about the roof stripes, 73 have the strobe stripe and I have seen some 74's with a solid stripe over the roof is this a 74 only thing? Next question is about the rally instrument cluster bezel, what is the difference between the 71-73 bezel to the 74 bezel? And lastly the speedo, should it be a 150mph or 120 mph speedometer? And auto trans console, tShift slap stik or Ball shifter handle?

Great Info THANK YOU!!!

I've never personally seen a 74 with the solid stripe, I think it might have been a late year thing. I've seen the ball shifter before, but the two of these cars I've owned with the slap stick both had the t handle shifter. My current 74 has a column shift, and it was an original 400 hp car. The 74 dash has the little icons next to the headlight and wiper switch, you can see them in the pics in the brochures. My current dash is out of a 73, and has a 150mph speedo. The other cars I've owned were all 120mph. So not sure what options you had to order to get those things.

The solid stripe was a 74 thing, as was the little icons beside the headlight and wiper switches. Physically they interchange with 71-73. My 73 satellite parts car was built with a rallye dash with the 120mph speedo and no tach. Did the tach option get you the 150 speedo? Slapstick should be a t handle.

these were all running changes in parts that will vary in respect to date based on which assembly plant

T-handle to round knob
150 speed-o to 120 unit
