Photo bucket does not work on sites, nor my browsers firewall. I suggest moving to another photo sharing site.
I use imgbb.com for quick sharing and linking of photos that I don't save and share here. |

If you use Firefox and the add-on Photobucket photos WILL display -- I could see the images in the previous post just fine. I guess that does limit you to using Firefox or Chrome (I haven't personally tested Chrome) though. Seems like someone would make an add-on for the Microsoft browsers... but they may not support such "tampering"...

I am aware if It, but I don't use add ons, and with android as my primary use of browsing, i am limited to Chrome Dev as a browser of choice. Mainly because of most all browsers have way too much going on, and do not have Samsung's builtin browser customisation ability to trim down some functions. Just a personal pet peeve at how things are with android. It was cool in the Jelly Bean and Kit Kat years, but now it's a Matryoshka doll of services that most users are unaware of when they use or install an app. |

Well, the Chrome fix supposedly works on Android devices... I haven't tried it as my Android tablet is too old and slow for much internet use (need to buy a newer one!).

Do you plan to keep the stock rear axle? Don't know if it will hold up to that kind of punishment.

The rear axle has really been a point of interest for this build. It has the AMC 15 with a factory open differential. My power output will not likely be very high (around 150 bhp at best) so the AMC 15/Dana 35 would meet my power needs, and it's light. As it is well known, the AMC 15 later became the Dana 35. I have read some contradictory information regarding using Dana 35 limited slip differentials and disc brake conversion parts on a AMC 15. Some places (older posts of this forum, not sure where) claim the Dana 35 rear axles use a different spline pattern than was used on the AMC 15 but I also found a differential provider (http://www.drivetrain.com/parts_catalog/positraction/no_slip_amc_amx.html) which claims by way of a table that the 1979 Spirit was fitted with the Dana 35 (or at least that the AMC 15 is close enough to the Dana 35 that the diff will work). I have looked at upgrading to the AMC 20, Ford 8.8 and Ford 9" but I haven't been able to find a complete unit that has the correct rear track width. I would like to stick with the AMC 15 if at all possible as it is the most cost effective solution at this point and I can always upgrade later. Also if any of the AMC 15 mods workout, I can use them on my Eagle which has the same rear end. I am open to suggestions regarding rear end upgrades (what will work, what doesn't). I am in a similar predicament with the trans but that is for another day.

I agree with you - with the relatively low torque you'll be putting out with the 2.0, your existing rear end will be just fine for awhile, and the open differential will likely not be a serious issue until you get the rest of the car sorted, and start putting down some competitive stage times. Then you'll want to look into a twin-grip unit for it. Where I'd be looking at spending the money is on brakes. Since the 2.0 gremlins 'suffer' from significantly better weight distribution when compared to the 6 cyl versions of these cars, converting the rear axle to disc brakes would be a good investment, and allow you to put a proper handbrake. While you can install a handbrake on the existing drums, modulating them is difficult. |

I have heard some information on grassroots motorsports forum that the Borg Warner HR-1 (the manual trans originally fitted with the AMC/VW 2.0) is the same as the Ford Type E (common 4 speed used in the MK1 Escort and Cortina). Does anyone know more about this?

Well......close. it's a BW SR-4, same transmission as used in the Pinto/Mustang II of the same era. for light torque applications, it's ok. At the time, it was the most advanced and light-weight 4 speed out there. Time has not been so kind to it's reputation. For your motor, and for getting started in rally, it will do fine, and will force you to learn the art of double clutching, as it is relatively easy to beat the synchros, especially when downshifting. I used this transmission for years behind my 4.2L in my 77 Gremlin for autocrossing, and it did OK at first. switching to synthetic gear oil helped the synchros keep up, but ultimately, I had to upgrade. I suspect you will too, but for now, if it is in reasonable shape, keep what you got. The 1st thing to check is the nylon bushing that rides between the shift lever and the shift rod on the top of the transmission tailshaft. if the shift lever is wobbly, I can guarantee that is broken or missing. I'm pretty sure the part is still available through Ford channels. Replacing it will restore 90% of the shift accuracy and feel, and will help prevent grinding, etc. Do you have a factory TSM yet for your car? It will describe everything you need to know about this transmission. |

in terms of rear end you'd be looking at
57-59 Ranchero and Wagon 57.25 inches (narrowest 9" housing) 75 Mustang II 8" 57.00 inches 65-66 Mustang 57.25 inches For the ford 9.0 if the spirit is a 57 inch length (not sure?). If its 56 inches it'll be tougher http://www.jegs.com/s/tech-articles/9-inch-ford-rear-axles.html&title=9+Inch+Ford+Rear+Axles You could go custom new but its not cheap http://www.9inchfloater.com/whatis.htm Edited by barriegolfer - Feb/21/2018 at 5:23pm |
