Glad to find an active place with Roadster people.
I'm not new to Roadster's having had them since the 80's. Have had 3 x 67 1/2's (1600's), a 68 1600 and a 66 1600 in the past. Currently I have a 70 SPL which was upgraded with a U-20 & 5 Speed in the 90's (the classic fake SRL). I bought my daughter a 66-1600 which she is learning to wrench on. Have had other Datsuns in the past as well (fond memories of 510's).
I know the cars decently having had to rebuild many R Series engines (Kids car is getting that treatment now), and have had to fix all the usual things we run into (can't count how many head gaskets I've replaced over the decades).
Currently the 66's head is out at a shop, all of the gallery ports are being ground out & rewelded, new valves and a shave. When we got that car it had sat for over 10 years and was seized solid (took a whole day to get the motor to turn). We've done a lot so far, always more to do.
The 70 got a new hood yesterday, and is getting a new exhaust Sunday (everything from headers back). I do all my own work, thus will be welding / cutting etc... myself. Monday is further work on the dash. I'm fabricating new steel for the top / bottom of the dash and will be making a flat dash out of zebrawood.
I know some tricks that may have fallen by the wayside over the years and if they can help someone in a pickle, always glad to pass em along (ie: a 510 starter flipped upside down will work in a 1600 if you're in a pinch. It spins the proper direction when upside down, and hooks in fine when te bendex kicks).
I've been a roadster fan since the early 80's, my favorite cars by far.
