[TR] TR4 shackle length

[THOMAS FANSHER]

I just replaced mine and the car's not handy to measure but I think 3" is 
about right.
Certainly no longer.
I had the same bottoming problem with 185X15 on panasports. I replaced the 
rear springs and now no problem with rubbing and she handles a lot better, 
too.
Getting the bolts out of the silent blocks was a LONG process using heat and 
PB Blaster, but eventually they came - does 5 weeks sound like a long time? 
If you have any problems getting them out let me know. First hint, use a 
fine threaded stud in the bolt through the frame - that way you're putting 
pressure on the stud not the bolt you're trying to remove, and use grade 
eight washers for the leverage on a socket over the bolt. I went through 
about 6 or so studs during the process, but the threads in the bolt were 
still good.
