There was a similar looking 79 that was running around Redwood City for a while. I haven't seen it lately. He was at the muffler shop getting something fixed when I stopped in and he was impressed that I 275/60's out back on my '77. Got kinda upset at me for having little to no rubbing issues and he said he was stuck with 235/70's because of his rubbing issues.
Thanks guys she hooks!! I have a little blown stroked smbc aluminum heads, roller valve train all that. Not!! The little 235's see allot of abuse! Not lasting long though...
