A few updates.
The TH400 in the car went out late last year. We pulled it out and had it looked at and it's not good. We really want to do a manual swap however we are worried about the time frame to get other projects done. We need to decide soon.
We are removing the 1-5/8" headers that were on the car and replacing them with 1-3/4". Finding a pair to work is tricky, we tried Dynatech and they didn't clear what we needed correctly. We have a set of Hedmans we are trying now. AFR recommends 1-3/4" with the heads we are using.
In the meantime we are also building a set of coilover only a-arms with additional caster built in. They are coming along nicely.
