Rob, we used a Tilton/McCloud (sp) hydro throw out bearing setup on our 65/340-451/833. We found the hydro throw out bearing was hard to bleed as the bleeder hose faced down (?) and the little cylinder they provided for the firewall had to be braced to the shock tower as the firewall was flexing! A motor brace bracket (from v8 motor to trans) was used on one of the cylinder mount bolts to the shock tower and it worked great, looked kinda stock as its still a mopar part. Hydro worked for us with a Lakewood LA/B bell and numerous headers.
