Exorcising a '78 ( and '78 and now '76")

So, the short nose starter is NOT the correct one for the stock rad4 bell housing. I can say that the starter off an automatic works. I am getting delayed disengagement about every 4th start. It appears the bushing in the nose of the previous starter failed allowing the gear to walk away from the flywheel. This caused damage to almost all the teeth on flywheel. Did the bushing fail because I have the wrong starter or because it was out of the used parts bin ? I don't know but for now she runs again!!!!

I know we cannot find new flywheels. I am afraid to go to far from home with it damaged. Since I want to eventually do the Power Tour I started to search for a used one. Look what I found. Modern Driveline now has NEW "lightened" flywheels for stock II's !!!!!!!!!!!! They come in both 28 and 50oz. New!!!!! I am betting someone over there has a II.

While apart I rebuilt the motor mounts. The engine barely moves now when revving. They make the idle.... harsh from the drivers seat. I do have an aggressive cam. I can feel the engine in my seat now. They also make accel and decel feel tighter. The whole car feels tighter. More responsive to throttle inputs. The engine sits a little lower now as I removed the spacers I was using due to the old mounts sagging. The air cleaner used to touch the hood scoop but now there is a little bit of a gap.

The vibration is improving. Certainly still there but better than it was. I still get it at 1800 to 2100 rpm in 5th, as well as 4th at higher rpms. I found the front seal leaking on trans. 2nd gear takes finesse to engage and one mounting tab is broken where it meets the bell. I would like to get a new t5 and flywheel from MDL this winter. I think that should resolve the rest of the vibrations. Actually I hope that it helps but that's my story to justify getting the better 1st gear ratio and a stronger transmission.

With the exhaust quieter. By no means quiet. Just quieter I can hear the body creaking constantly. I tightened the subframe mounts which helped a little but the traction bars make all kinds of noise. At least I think it's them. Anyone else using the stumpys traction bars? Do they make a lot of noise or do I need to redo another item I thought I done did right? lol

Mine do. I also had the tail pipes hitting the subframe connectors but only on deceleration. I cut them off for now. So the only noise I've got now is the stumpys.

I am fairtly certain the vibrations are coming from the trans. I can run 4th gear to 4,000 rpm with minimal vibrations. Once i drop into 5th they start and continue until I drop below 45mph. The front seal is leaking and leaving larger and larger puddles.

So I sold some old crap laying around and ordered a new T5 from Modern Driveline. As always I was a day late and have to wait for another batch of input shafts to be machined before they can build and ship it. Looking at about 3 to 4 weeks. I basically went with their conversion kit minus cross member and bell which I already have. This way I can eliminate everything old in the driveline.

I also ordered a 2nd clutch, sn95 input shaft and steel bearing retainer for my old T5. It's going into one of the other cars with less hp once rebuilt.

I was informed the T5 conversion cross member manufacturer is no longer in business. MDL attempted to contact the company who bought him out but they are not responding. MDL told me they were going to start making them in house but they did not have a firm timetable as to when.

Try one of these at CAR. It's what I used with my MDL kit and worked great.

I picked one up from CAR last year when I installed the used T5. I just wanted another for whatever car the old t5 goes into. I havent even decided which car that is yet so I am gonna wait.

Enzio- you used MDL for your t5 correct? Are you happy with everything? I have a cable operated clutch and Rad4 bell. Otherwise I will have a very similar setup as you.

Yes I used MDL and bought the 1352-251 (I think that the number. I'd have to look it up to make sure.) I'm very happy. Next spring I'm going to enlarge the shifter hole slightly as the shifter rattles a little bit in 2nd and 4th because it's barely touching the hole in the tunnel. If you're buying the kit then get a bent shifter as I had a straight one and my knuckles were hitting the radio knobs. I switched to a hydraulic clutch kit as I'm using the spec clutch from CAR. (now MDL has a stock replacement but didn't when I bought mine) I imagine if you're using a stock replacement pressure plate the cable operated one will be fine.
