I appreciate your correction. Better to get it wrong here and stand corrected than getting it wrong in a national publication and being ridiculed. I also would like to learn from this. Could you give me some examples with regards to conversions and backthrust (via email or PM...my email addy is stated earlier in the thread)? Also how I'd calculate how much a '98 safety lug could take? I thank you in advance and will change my approach accordingly.
