I installed the Precission one piece door seals on my '71 last weekend, and they are slick. The doors were initially difficult to close, but once closed and left for a day in the 105 degree desert heat, they compressed and fit like new allowing the doors to close easily. If you use the one piece, be sure to clean everything off under the original welting down to metal for the best fit.
Thanks for the input guys - my mechanic has made the line switch and mounted the new wheels & tires. A few more things to check and I'll be on the road next week. Getting the Z roadworthy after 15 years in storage has now cost just a bit more than I paid for it NEW in 1971. Oh well.
I searched the message archive and think I know the answer, but need validation before I talk to my mechanic tomorrow. My Z has a 4/71 build date. I bought it NEW, however it's been sitting for years and I had all the brakes replaced - including the M/C. My mechanic used a later M/C. I've read that the reservoirs are switched on late '71 M/Cs and the lines to front & rear brakes need to be rerouted if going from an early to late M/C. Is that correct? Input appreciated.
